I know. MS needs to come out and say something. They have been too reserved in all this. Especially if it something like this that a lot of people will be pissed about. Required online connection is a touchy subject, so it would be in their common interest to at least out that as false if that is the case. Honestly I wouldn't even consider it if it did require it. I have a shoddy internet connection so depending on internet connection is a big turn off for me. Main reason why I was done with D3 after one playthrough.
Microsoft have their own event scheduled for April, right? I don't think they have to say anything until then. This is still rumor and speculation.
