Considering Capcom has yet to announce any 'next gen' games, I think it has nothing to do with Wii U or any actual console and everything to do with the fact that they are simply not currently making a 'next gen' game. They are just telling their investors that it takes time to build a game with new engines and they need to get focused on that immediately, in earnest, as the next gen cycle is beginning.
I really think the OP is looking way too much in to that sentence.
