Talking about the "Off-TV Play" feature.
Since it seems that will be one of the most used features on the Wii U.
Do you think that it could stay as a standard for the future consoles? (No PS4/Xbox, but the generations after the next one).
Standards are defined by just that: a standard expected by consumers. If the Wii U explodes and the concept of off-screen gaming becomes a frequently used and expected hardware feature for consumers then yeah, everyone will jump on board.
Nintendo won't be the only ones pushing it. Apple is arguably already doing their own version of "no computer/tv" peripheral with the iPad and succeeding greatly. I figure their TV systems will offer something quite similar, integrating iPads into the home network.
Success is at the behest of the consumer though. Take 3D for an example. I for one feel 3D is a gimmick for film. But for video games I think stereo 3D objectively enhances the experience. I
love 3D in gaming. But consumers don't seem to really care about 3D, and though Nintendo banked on it I don't believe the glasses free 3D of the 3DS is the strong selling point they desired. Consumers don't seem to care much about 3D in the grand scheme of things, thus it probably wont be a marketed standard.
I wonder if the "off-tv play is worthless, that's why most people have multiple TVs for" argument is ever gong to die out. That's my personal favorite. Personally, I don't enjoy quitting my game and packing up my console and moving to a different room every time someone needs the TV I'm on, but I suppose that is just me.
Off-TV play is cool. But I'm pretty confident it will be a niche selling point in the west. It's a design feature derived from Japanese thinking, targeting the Japanese market where households are much more likely to have only one TV
and smaller space. Though I only have one TV, I know a lot of people who have two, or don't really find their TV gaming time invaded by other features. For these people off-TV gaming is less of a big deal, and this will be common for the American market.
