I think it was an amazing marketing move on their part, including the cross-buy content.
I feel like a LOT of people who weren't buying one otherwise will definitely change their tune.
I was eventually going to pick one up anyways for Uncharted, but this is just another must-have title for me that seals the deal.
I got a Vita back in June and I recommend you all do the same. People love to say how starved for games it is, but I've gotten much enjoyment out of it so far because it's just an all-around excellent device and deserves to succeed.
I got mine for Uncharted, Gravity Rush, and WipEout 2048. Down the road I'll probably be getting Tearaway, Super Monkey Ball: Banana Splitz, Sonic & Sega All-Stars Racing Transformed, and of course, the free Vita version of PlayStation All-Stars Battle Royale.
