I wouldn't be surprised. There's really nothing being done here that cannot have been done with him as 10, I agree with those upset about the change in that regard. If Superman's going to have a family, it should definitely be werid, I agree with that, but again weird and teenager doesn't necessarily have to go hand-in-hand. So I tend to lean toward your way of thinking on this, that it was more of an edict. If so though I'm in full support of it if moving away from Superdad was at all a factor.
If it is more of an editorial thing, I would start to doubt the chances of it being reversed even after Bendis.
