You make a good point actually Andrex :
Previous tech bracket : 3DS, Wii, Xbox, PS2, GC, PSP
current tech bracket : X360, PS3, Wii U, Vita
the Vita and Wii U add two extra potential streams for companies who don't want to shift off current tech - so maybe the Wii U can help the Vita? I mean - if you're a 3rd party you might as well port across to Vita then you can have a chance of hitting at least two platforms where you games aren't going to sell rather than just one.
