I'm 100% in on this one as my 2nd retail Vita game purchase to follow up Uncharted.
Same for me. I just pre-ordered on Amazon using $10 in gift cards, so $30 shipped. Using Swagbucks as my search engine pays off. That's how I earn the gift cards. I'll be sure to put you folks on my PSN friends if you're not already so we can do co-op.
