A user friendly interface. Blu Ray play back, maybe even more media options. A traditional controller. Good 3rd party exclusives, to name a few, plus yeah the things you said and I don't know maybe a better eco system, more video and web services than just the bare minimum.
Let me rephrase it. In order for me, personally, to buy an NX I either want it to be something that gives me an experience I can't already find else where. I won't be buying another Wii, or a Wii U. If they can't prove up front that it will have games I want and features I want then I won't be buying. Not unless it's real cheap like $200 at launch which isn't going to happen. Honestly what does anyone want from a Nintendo console? I want it to be able to get 3rd party exclusives and the same types of games I can get on the PS4 in addition to the Nintendo games. I don't mean the CoD games I mean the Street Fighter games, stuff that you know used to be and should be on a Nintendo console.
If all you want is for it to play Nintendo games and nothing else then that is why Nintendo is in the position they are, they shoot for the bare minimum and don't even try to reach for anything better anymore.
I mean damn the Wii U couldn't even run a comparable Netflix app for over half of the systems life. If the machine can't convince me that it belongs in my living room sitting besides my PS4 then it has to be second console status and for that it needs to be dirt cheap.
I am hoping it will blow me away. It will have great specs, it will have great games. Look the only reason people care about specs is because developers care, if Ubisoft says the machine is underpowered and would require too much effort on their part to make games for it then they won't.
In order for it to have great exclusive games it needs to be better than PS4 to some degree. Now granted to be fair the bar is lower than Wii already because it WILL be HD so it's not like choosing between an HD system and a not HD system so as far as specs go it will already be on a more level footing anyways. Gamers won't notice if a game isn't sporting all the latest little features whatever they are, as long as it isn't obviously gimped from the start. Genesis was lacking in a few colors compared to SNES but for the most part it had comparable graphics. It sold just fine and had plenty of multiplatform games. That is what Nintendo needs, they can be weak in one area as long as it's not so obvious it hampers development. With Wii even if they had a fast enough CPU and a strong enough GPU to render Halo 3 quality graphics, not being HD was more than obvious for most people.
For Wii U, I don't think most games look all that bad, even compared to my PS4. Now if NX comes out and has a super fast CPU, plenty of RAM, a very powerful GPU but it runs say a slow system Bus or whatever to save heat or whatever and that throws a wrench in the whole damn thing. Bottom line it needs to have the same features as the competition going in and then something the competition doesn't have.
The choice between PS4 and Xbox One comes down to minor things and the games. If the choice is something like games vs. no games, HD vs. SD, or 4K vs. 2k, then most people will go with the better of the choice. Wii sold pretty damn good all on it's own but the HD consoles sold right behind it, and they combined sold twice what it sold in the end.
I guess I just don't want a system that is going to be a lame duck out of the water. You can interpret that however you want. If it doesn't sell me up front then, maybe like Wii U it might in a few years but there are probably more people like me than who will buy it just because and I am still fairly open to Nintendo games anyways.
