Diablo 3 was never announced to be PC/PS3/PS4 only, so it wouldn't surprise me. They announced it at a Playstation Meeting, so it's obvious that they wouldn't talk about a Xbox version.
There are quite a few things that would point towards a Xbox release.
- A screenshot showing the 360 buttons in-game
- a Blizzard dev saying that "we're not necessarily a Sony exclusive."
- a forum post on the Blizzard forums that pointed to a Xbox release but then got removed.
- now a retailer listing
The console version itself was rumored also a long time ago already.
