Many Japanese companies prefer handhelds, period. PSP showed it, 3DS shows it. It's a safer bet in Japan to release your game on the leading handheld. That's why this 2-in-1 idea is a great way to unite western and Japanese strengths for Nintendo.
Only that they don't want to lose the sales of a console version. Third parties have no problems of selling Vita/Ps3/PS4 versions all the time.
And I'm not sure what people imagine how largr the power gap between handheld and console is. If it ends in a similar way as the Vita and PS3 (I don't think that the console version will be that underpowered) ten there are many games designed for the console market which just wouldn't run on the handheld.
