Wow @ this thread. If you're smarter or more skilled in some things than your twin brother who does better in other things and is perhaps taller or more muscular or whatever, that doesn't make you part of different generations, folks. Seriously. Also, the WiiU does things no other system before it did to that extent. Whether it's the things you want or not don't disqualify it from being a new system part of the next (soon current) generation alongside whatever Microsoft and Sony will put out. Its level of success (so if it gets ports or not) won't determine its status either, as it didn't for the Dreamcast, which wasn't kin to Saturn/PS1, but to PS2 etc and as it doesn't for the Vita (it won't suddenly turn next/current gen if it starts doing better and getting more games, it already is).
@MasLegio, no, it doesn't have current "tab" hardware because a) it's actually a gamepad, and b) the whole point is the console does the processing, so it barely has any hardware. Maybe you should look into what you're trying to ridicule a little bit beforehand.
Nothing stops Microsoft or Sony from using the latest (and greatest, not just in features but performance as well) PC hardware to do their next systems either, outside financial viability and intended goals, so saying consoles have a given generational hardware level that sets them apart from PC and leaves WiiU only behind is silly too. They all decide what to put in their systems with the same criteria, ie, what's best for the company, not what's truly the latest and greatest technology around.
