I mentioned it in my last post
It's been out for a few days. Sony's been running some ads on TV, but other than that, I only knew it was out because I saw it on a list of this week's releases.
It's pretty damn close to the original. There are only two planes instead of three, and respawns are infinite (though they cost you points), and there's no multiplayer, but aside from that, it's exactly the same.
