As prognosticated by the ESRB, Darkstalkers is indeed headed to PlayStation Network. Capcom has confirmed that its monster-infused fighter should arrive on PSN later this month, with the release currently slated for November 29.
Readers may remember that the road to Marvel vs. Capcom 3 was paved with downloadable releases of Marvel vs. Capcom 2. We've said before that this PSN release probably doesn't mark the beginning of a Darkstalkers revival, but there's always hope.
