That's not necessarily true. It's not difinitive that they have said they will stick with the PS3
“We're not working on anything for PS Vita. I won't say never, ever, but there's no plans for it right now - we've always felt that consoles play to our strengths as a studio the best”, stated Meyer.
So they may in the future but that is definately not a no which is good enough for me
I can't believe you are getting any hope from that, ND have never made a portable game and after that statement I would just forget about it ever happening.
I've just noticed that you're not on the PSN list. do you have a Vita?
