During an interview Bashiok (sp?) said that no store will know release date until they make an official release and that they can not stop a store from making up a date. Best buy has been told to take the poster down by a GM (I am guessing this stands for General Manager.).
It may make you happy Surtur that the word is they plan to release Diablo 3 on Consoles as well, it probably will be a while though, not at the same release time as pc.
