Kind of bored about talking about this ps3 nonsense BUT when I went to there website to read that message they posted about the leak
http://www.bungie.net/News/content.aspx?type=news&cid=32112
There is a giant "BUNGIE IS HIRING FOR PS3" banner on the right side of the website.
Has that been on there website for a while now or is it Bungie winking and nodding "hey.. we are totally working on ps3 so shut up about it".
The only reason I would see there new game not being day and date for ps3 if there was some Microsoft shenanigans. Activision would love to get the game on as many platforms as possible and would probably help bungie with extra help if needed to make it happen.
Bungie probably would want it as well because its more money and exposing themselves to a wider audience on ps3.
Waiting for the ps4 would be a bit silly since the audience is gonna be a fraction of the ps3's.
Also reading that document again and you know what kind of stands out just a little? No Mac version mentioned.
I know mac gaming isnt really a thing but I would have guesses for old times sake Bungie might have tried to get something out on Mac.
