Wii U is 7 years too late to be called next gen. Can't call a system that is less powerful next gen.
Generation doesn't have anything to do with power. It's the time period when all manufacturers are in competition with a certain product. Nintendo created the weakest product last-gen so have jumped ahead this gen. This means that they'll be getting 360 ports until the PS4/720 come out, and will struggle to handle them.
The Wii U is more powerful but not by any significant amount. It is still 'next gen' by definition alone. --- PSN/GT/Steam: Ravendust Reviews are a metric of quality. Sales are a metric of popularity.
I'm a Nintendo and Sony Fan, I like Nintendo's exclusive's and Sonys Exclusives, I have my Wii and PS3 side by side at most times and before too long it will probably be Wii U and PS4.
Having said that, i don't know where you got information from that the Wii U is less powerful, it's actually more powerful then PS3, but that doesn't matter as I still enjoy retro games, just saying you're wrong it's all...
And as for bad ports like mass effect 3, that's ea's fault, not nintendo's. --- Uh, this is a wrestling match, not a mutual admiration society! - Jim Ross (WWF War zone N64 -1998)
