It's not all about processing power though. The PS4/X1 have zero innovations. Just small improvements on what we already have.
The Wii U gamepad actually did something new.
I guess Microsoft and Sony both thought it was cool, so they copied it with smart glass and vita remote play.
Smart Glass pre-dates the Wii U, and when MS tried to innovate at E3 2013 look what happened.
Can't really blame them for going along the safe route after how the media shot them down
It's Cel Shaded though. I can understand I'd we were looking at the 2011 tech demo but this doesn't look like a very demanding game. They already admitted it was 30fps.
