I think it's a bit too early to be calling vapourware on that title... it could just be that it wasn't at a stage at E3 where much could have been shown. I'm quite sure there are alot of games Sony has in production at the moment that they haven't announced yet mainly because:
A. they've already announced a metric tonne of stuff for 2011 and want to keep our attention on those games.
B. they want to keep come surprises for the big trade shows (gamescom, E3 etc).
We haven't heard or seen anything more about Twisted Metal PS3 since E3, and we know that game hasn't been canned. ;-)
Point taken, though for this game we havent seen it since E3 2009, not really much like twisted metal at all
