Sony recently showed off near-final builds of its next wave of original PSN games, and even committed to release time frames, according to MTV Multiplayer. Though weekly releases on the PS Store are largely kept behind the big, black curtain until showtime, it appears that Sony is trying to steal some attention away from the recent bevy of WiiWare boloney "buildup" and the well-oiled Xbox Live Arcade machine by generating previews of its own. So how 'bout those dates:

Late April: PixelJunk Monsters Encore (expansion pack)
Early May: Echochrome
May: Elefunk
Late May / early June: WipEout HD
