I've got a couple of friends that have the game; one has it for PS3, the other for Vita. They really like it. I liked what I played of the beta, too.
I always see it on sale, too. It's rare that some major store doesn't have one of the versions for at least $20. I didn't like what I played of it in a store with my brother and none of the characters really interest me at all so I haven't picked it up but I'm kind of interested if only to support the idea of cross-play.
I got it with my Vita, but I've only played it once or twice. Wasn't overly impressed by what I played, though I'm sure it'd be a lot more fun with other people rather than solo. I'll probably give it another chance eventually.
