I noticed that BBTS has sent out notice that Mattel has told them that future waves of DCU All-Stars have been cancelled (I personally got a cancellation notice for Larfleeze, etc.) There were previously three waves scheduled - those were all cancelled, and a new Wave 1 has gone up for preorder, consisting of:
Batman (New 52)
Superman( New 52)
Not sure what that says for the line's future - maybe it is just a reshuffling of things, or maybe they are changing their minds on this line in general. We'll see.
