PlayStation Network Forum

So I've been playing a bit of Marvel vs. Capcom 2 and it reminded me of Darkstalkers on the PSP. I remember once upon a time from a few news articles that a bunch of Capcom games were being put on to PSN, such as Mega Man Powered Up, Mega Man Maverick Hunter X, and Darkstalkers. So I hop on PSN and lo to my surprise none of those were there. I still saw the Power Stone Collection and Capcom Classics Collection, which were a part of the games being put on PSN, but what happened to those others? Were they ever on there or have they yet to come out?
