From what I've (quickly) read online, they were going to do the same with NBA 2k11, but they had online play issues in 2k12 so they kept the servers up a little longer for 2k11. But I would imagine 2k13 will similarly go away next November.

This is 2k, after all. We might give EA shit about cutting costs, but 2k and their parent company are trying to murder costs

And I only mentioned the manual because Smooth said "no notice". I wouldn't expect anyone read that.
