Sega has unveiled their upcoming line-up through the first quarter of 2009.
The biggest thing to mention here is a release date for Sonic the Hedgehog's next grand adventure, Sonic Unleashed. It'll be shipped to stores this November on the PS3, 360, Wii and PS2. Sonic Chronicles, the DS-only RPG being developed at BioWare, will arrive two months earlier in September.
Other big names include Golden Axe Riders for the PS3/360 and a follow-up to 2005's Yakuza for the PS2, both due in September. Gearbox's Aliens: Colonial Marines, a game we've seen nothing of since its announcement in February, will be out in the first quarter of next year.
