Take this with a grain of salt, but an interesting little document popped up on Sega’s PR site that mentions quite a few details that the two companies are in discussion about. These include:
-PS2 emulator on PS3, the document citing games such as GTA Vice City and an unknown Sonic title.
-Consideration of import titles on PSN, menus translated. Yakuza was brought up as an example of a game.
-Sonic All Star Racing is open to DLC characters to differentiate the PS3 SKU. Not Ratchet and Clank, but others are likely.
-Sonic Anniversary is a proposed project that would put a ton of Sonic games on one blu-ray. SCEA would love exclusive power-ups and different game modes.
-Dreamcast digital title support. While not exclusive to the PSN, the proposal is Sony can pick which titles it wants more, with long exclusivity meaning more marketing support for Sega.
For the full breakdown of the document, hit up the jump.
