Amazon has listed part of what can be expected to hit PSN on March 15 and March 22, and if correct, the recent ESRB listing for Parasite Eve was indeed something to smile about.
Highlights for March 15 include: Parasite Eve, DLC for Hyperdimension Neptunia, ModNation Racers, Mega Man: Maverick Hunter X, and Ultimate Ghosts 'n Goblins along with DLC for Ar tonelico Qoga: Knell of Ar Ciel.
Highlights for March 22 include: New costumes for LittleBigPlanet 2, HOARD, Hyperdimension Neptunia DLC, SWARM, and Ys I and II Chronicles - $24.99
Since this did not come officially from Sony, don't take it as solid-gold just yet.
