As a home console if you are looking at Nintendo you are looking in the wrong place since about 1995. They have pretty much cemented themselves as a second console. But as a handheld they have always been IT, as in the only game in town that really mattered. This is about as close to pleasing everybody as they can ever get. Is it going to convert die hard Xbox and PS fans over? Not likely. Is it going to attract people that bought those consoles because the Nintendo offering was lacking in some way, sure very likely.
I see the console space like this. There are the PC gamers that can't afford PC gaming who buy an Xbox.
There are the Nintendo gamers, the old school old timers who grew up with what we call today retro. They split, half of them went to Sony, the other half split in two between Sega and Nintendo. The Sega fans split after Dreamcast into thirds leaving them a small, insignificant but highly VOCAL minority on the web. They are the ones that vocalize the most negativity towards Sony and Nintendo out of spite.
Then there are the Nintendo loyalists which are divided between the console and handheld units for obvious reasons. The console typically has the larger more "epic" games while the handheld tends to have the more pick up and play retro style games. The problem is the handheld has caught up to what most console gamers wanted and the console became stagnant so there isn't any reason to buy both systems because the console barely did anything the handheld didn't but usually the handheld had at least 30-40 exclusives the console gamers wanted to play but not badly enough to spend the extra $150 + to do so.
So the Sega fans will do what they always do, the Sonic fans will buy the Nintendo console and wait and see, everyone else, that's it Sega doesn't have any fans left just Sonic fans. So that userbase is gone they don't count anymore there were maybe 5 million of them total they are not dwindled down to maybe a million or less.
The SNES fans that migrated to Sony are the harder ones. These gamers stick with Sony because it's their best shot, its tradition at this point. They were Nintendo gamers for 2 generations and Sony gamers for 4 generations so their no longer Nintendo gamers. These are the gamers that bought a Nintendo for the 3rd party greats like Castlevania, Mortal Kombat, Street Fighter, Doom, Final Fantasy, those games left Nintendo their fans did to.
Now they have grown up. This is where it gets tricky. The kids who grew up with Nintendo that split along those above lines, they are as divided as ever. But they DO have very strong warm emotional feelings for Nintendo that can be used to bring them back, but they need convincing most want something that doesn't skimp on the expected features. This doesn't have a disc drive and is not intended to be a Blu Ray player. We have come to terms with Nintendo consoles not playing movies on media. Okay but the world has now changed the tables have turned, nobody cares about disc media anymore they all watch Netflix. So that is no longer a deterrent from the Nintendo console.
Wii U was the last console that should have played movies on disc that didn't. But that wasn't likely a factor so its out.
Then there are the kids that grew up on Playstation. They never played the games the Nintendo gamers are fond of but they did experience the 3rd party games, the same ones. This is what unifies them, FF, Castlevania, Doom, Mortal Kombat, Street Fighter, Resident Evil, Metal Gear, etc, they are loyal to Sony because that is all they have known. Even the PS3 had a slow start it still had the games they expected it to have so they stuck with them.
They are locked in. Nintendo can ONLY win them back if they have the same stuff Sony does and Nintendo stuff but they aren't that excited for the kid friendly Nintendo stuff so they mock the rest and shrug them off. Those gamers are out they are firmly locked into PS4 and maybe are drooling over PS VR.
Then you have the casuals. These are the gamer that ONLY play their favorite sports game with their friends and pick up a few online shooters to say they are gamers but they don't really fit into the gamer culture. We call these people dude bros in a negative way but their a majority of the gaming public. They laugh at Nintendo for their unusual decisions. They might be enticed to get the Nintendo console, like Wii, if it has something they want, something cheap with a good party vibe. These gamers are always in flux but most of them want the latest console to play with their friends, they migrate when they have to, when the old consoles stop giving them new Madden games. This has been the hardest segment for Nintendo to keep because they are one segment but Nintendo thinks they are two. Nintendo thinks the Wii Sports gamers are into Wii Sports because it was pick up and play and not because it was a sports game. Nintendo thinks their Mario Sports games are real sports games and don't get why the casual gamers but hard core sports fans mock them. These gamers also pick up a Halo or GTA on the side because it's "cool".
The kids coming up, the new teenagers and the gamers coming into the mix are always up for grabs. They are the reason there is no brand loyalty in the larger market. This is why the Atari loyalists didn't flock to the NES when the kids coming up did. We knew about Atari, many of us seen Atari or had played Atari but Nintendo was where it was at. Our younger siblings they came up on Sega and SNES the rest split and went to Sony. The kids coming up loved Playstation because it had Crash, Spyro, Lego, etc.
Xbox is the odd duck. They literally have no reason to exist their machine is just a PC for the living room. PC's are dead gaming has moved on so I don't see them lasting for much longer so that leaves room for Nintendo and Sony to swoop in and pick up those gamers. There are loyalists to Xbox who are into the multiplayer scene and Nintendo can win them over easily if they can do multiplayer right and it looks like they did. Xbox did multi better than GC it had the 4 controllers local and it had Live. But Live is no longer and advantage for them.
That is way more than I set out to type most people will skim so there it is my ramblings for the day.
