The Diablo 3 beta will be released this summer but you can already pre-order the game for PlayStation 3. If this will actually be the case when the game is released is not officially announced by Blizzard.
This is still a rumour floating around but if it’s true then I have a feeling of that Diablo 3 on PC/MAC wont be the same game on PlayStation 3. At least not on the competitive level where you relay more on your speed and the ability to use many different commands at the same time. Also the competitive and more hardcore players will choose PC/MAC since that will probably be the biggest of them two.
I really hope that this is a joke and that we will see only one game; the one for PC/MAC.
