I think they will likely be considered 8th gen in the same way the virtual boy would be considered 8th gen.
But what makes something fit into a certain gen? Is it a matter of power because the Wii and Wii U both would fall into a previous generation. Is it a matter of timing because if so the dreamcast exists in it's own little world.
Is my aging desktop which is basically awaiting the scrapyard despite coming out in 2006 considered to fall with the 7th generation despite being unable to run far cry at a framerate of more then 6 fps. If I successfully manage to repurpose the hard drive as an external drive for the Wii U would it become an 8th gen system by association?
That was sort of my assertion. I think a generation should be hardware based, not timeline based but I think each market should be defined, hand helds are in their own generations separate from consoles, if that helps.
It also depends on what you consider a console, where does V Smile fit, or Tiger hand helds, or plug n play tv games? Or Atari Flashback consoles?
I think we need some simplification sure but we also need to keep things defined in an organized manner otherwise it gets too confusing. If you think V Smile is a game console which generation is it in? I consider it education toy and not in any "generation"but again what is a generation, hell even in people generations are not clearly defined, who here is Gen X, Gen Y, Millennials?
I don't mean to be rude I want to offer ideas but I really think that people use the word differently, in fact until recently there were no talks of past generations or numbering gens, they just used the term next gen to refer to the new product, hence my reasoning because it fits what was the norm for a long time, now what is being retroactively applied.
Let me ask this, what is the first gen? Do you count Pong consoles, or do you start with Odyssey or VCS? Which generation is the Intellivision or the Coleco Vision they can't be the same their hardware is too different and they were released in different times frames. Who decides is what I want to know and what is their criteria. Are you just going by Wikipedia or are you only curious so you can edit Wikipedia?
Up until about five or six years ago there was no numbers to the "generations" this is a new thing that began with Wikipedia and other gaming fan sites. Wii U is Nintendo's 8th console so it is their 8th generation gaming console, PS4 is only Sony's fourth generation of Playstation it is not an 8th gen console.
The "current gen" is technology based by most accounts, even developers the people who make the games refer to Wii U as "last gen" only ones who refer to it as current gen or next gen are fans. For Nintendo it is next gen because it follows their last gen, but it is not current gen, it's not even current it's over a year older than the new gen. In smart phones generations last a year tops, in PC's they go from OS to OS, so there is that. With video game consoles things are not any different than any other field, these game consoles are new to market they are in their first generation when a new batch comes out they would be in their second generation. You can't just lump all "video game" players into a single entity and a single generation, that only began recently and as far as I can tell NOBODY agrees on what it even means anyways.
So to recap, NO they are not in the same league as game consoles so they are not even in the same generation, they are not in the same hardware category so they are not even competing they are a different market reaching a different audience period. There are TWO current gen game consoles Xbox One and PS4, when Steam Box or Steam Machine releases it will be in it's own generation, and so on. Generations are arbitrary and pointless get over it.
EDIT: The only reason people care is so they point to the best seller and declare it having won the console war that generation so take that into consideration and reevaluate why your even interested in the first place.
