There's always the possibility that this is simply a boxed release of the ports of Sonic Adventure, Crazy Taxi et al they've been utting out for PSN/XBLA.
And why would Sega of America release games from Namco Bandai and Capcom?
It's Propeller Arena, and it wasn't officially released, but it's out there, I still have the image file on my hard drive actually, along with Ikaruga and Half-Life.
If it's being released by SEGA it is unlikely to have and 3rd party games, I expect Space Channel 5, that Ferrari game maybe, perhaps SEGA GT, but maybe not games that require special peripherals like Samba de Amigo and HOTD.
I miss my DC, I had over 80 games at one time, really a great console. Played backups with no modding required too LOL!
If they're gonna do a boxed release of the games they've already announced are getting/or already got PSN/XBLA ports then it will also include Space Channel 5 Part 2 and Sega Bass Fishing.
Could a mod fix the title, btw...
