According to Sega, each title will include online leaderboards, re-worked graphics (using smoothing filters, not HD upgrades) and most will feature network play (Comix Zone, Phantasy Star II and Shinobi excluded). No word on pricing or release dates but Sega plans to release the titles separately this summer, with Sonic & Knuckles appearing last. Why the delay? With Sonic & Knuckles, Sonic 2 XBLA and Sonic 3 XBLA owners will be able to use the classic lock-on feature from the Genesis-era to import Knuckles into each classic adventure. Of course, if patience isn't your best quality, you could just buy Sonic's Genesis Collection now (which doesn't support lock-on).
