The following unreleased Xbox Live Arcade games appear to be going around the internet at the moment:
Metal_Slug_XX_XBLA_XBOX360-JSteam
NEOGEO_BATTLE_COLISEUM_XBLA_XBOX360-JSteam
RAYSTORM_HD_XBLA_XBOX360-JSteam
Sonic_Adventure_XBLA_XBOX360-JSteam
The_King_of_Fighters_2002_Unlimited_Match_XBLA_XBO X360-JSteam
Im sure we all knew about Sonic Adventure and Sonic 4, hopefully the leaks of those arcade games might encourage Microsoft to release some of the titles. It would make a nice change from the flood of poor games that have been released on Xbox Live arcade recently.
Screenshots of more yet to be announced games have also been leaked including Quake Arena Arcade and Crazy Taxi. I also have it on good authority that Doom 2 will be released on XBLA in the future.
