I've heard of people getting MMS on their phones ever since last week. So I think AT&T is rolling it out as they go. Some people are reporting it by region, but if AT&T has to remove the opt out from accounts manually, I doubt its by area--more like account by account. So I think their goal is to NOT enable it for everyone on the 25th, but be completed by the 25th. It'll work fine. I will rarely use it.
