Scattered reports from the US suggest that Microsoft's first party Xbox 360 games are starting to ship, despite the fact the console itself won't launch until November 22nd.
Both GameStop and EB Games are listing Kameo: Elements of Power as available to ship within 24 hours, and various gamers report receiving it.
So far there's been no sign of the same happening on this side of the Atlantic, however, where Xbox 360 is set to launch on December 2nd, although most shops are full of placeholder boxes and other point-of-sale promotions. Retailers are expecting actual stock closer to release.
Games going on sale this far in advance of their home platforms is unusual, but it's not the first time games have made it out before consoles - some PSP games, for example, were widely available in the few days prior to the console's launch in the US and similarly in the UK.
