PS Vita and PS3 cross-play 'easily' rival Wii U, Sony says

[LinkVPit]

66 million people have a PS3, 3 million have a PSV so are developers going to support something only 1 in 22 (at best) gamers have access to?

I'm sure it can do what the WiiU can, but the low user base and high cost must surely cause big problems?
