That all having been said, SupCom 2 seemed to sell well on Steam, so I don't really think GPG is having issues financially. They might be having trouble finding a publisher, however.
I figure that is the case as well.
Sorian has commented on the GPG forums that they are still there, but nothing past that. While I can't imagine them folding up shop without letting people know, it seems odd that a company would make such a big fuss over letting users see a game being developed from the start and then just shut up entirely about it.
Glad to hear that Sorian is still around at least. Hope things go well for GPG. It does make me wonder what they are working on, though. They've got to be doing something... patching supcom2, working on kings/castles... anyway, hope to hear something from them before too long.
