The Xbox 360 and the PlayStation 3 version of Diablo 3 will launch September 3, 2013, according to a Blizzard post today. This is the first time that we've heard of D3 appearing on the Xbox 360. We heard back in February that D3 was headed to the PS3 and PS4.
We do know that the PlayStation version of the game will play on a different realm and not be accessible by PC consoles. It's probably safe to assume the same will be true for the Xbox 360. We don't know if these console realms will be able to interact with each other. The console versions o the game are also having their UI updated to a more console-friendly format.
The play testing on the PS3 version of Diablo 3 has generally been positive. Blizzard's move to bring the game to the Xbox 360 bodes well for it appearing on the next generation Xbox console as well, although no announcement has been made there. Diablo 3 is expected to have its first expansion announced at BlizzCon in November this year.
