Diablo III for... PS3!?

German retailers keep listing a PS3 version of the epic Diablo III game for pre-order, could this actually be something revealed at E3?

Blizzard has given interest into bringing their games onto consoles, especially this one, and also they've hired new employees for a "special" project not too long ago. This could be a hoax, but is it really? Sony has made no confirmation cause they don't answer anything that's rumor or speculation, at least not until those rumors and speculations are proven more so. If it is true, the German retailers list it as being only available for PS3, as a console form of course. This would also make Sony loads of money, since this is a huge game trilogy and Sony would need the money.

So what are everyone's thoughts? Is this a good idea or something uninteresting?
