Via Massively, I notice there's a bit of a random clue as to the fate of APB. The website and such might be dead, but for some reason the patcher is still delivering info. On the 22nd it read: "It's looking like there might be light at the end of the tunnel for APB. The end of the administration process is apparently close and there appears to be a buyer for the game."
A wind up? Wishful thinking on the part of remaining APB admins? It's hard to say, but both Epic and Codemasters have been connected with the game. My money is on one of the big F2P publishers, personally.
