I have often wondered, does it really matter?
I mean, if you're not confident the game is going to come out and have a preorder, then cancel the preorder. If you're holding out buying a different game because you really want AP instead, make your best call. Right now it seems to be delayed, so get the other game. At best it's delayed. At worst, you have to get AP a little later.
If you're like me and didn't bother preordering, my life really is not that affected whether or not the game comes out now or later.
