While browsing Amazon, I came across Sonic 360, which is said to be released in the UK on December 2nd, 2005, for the Xbox 360, but not PS3. I'm a bit skeptical, since it was revealed only a few months ago, but Amazon is an offical website...
I think it's a typo, and they meant to put 2006. But check it out and see what you think.
