I talked to MonkeyGod at Origins and they told me then that
Frost & Fur was their last release. Financially, it didn't make sense to spend four times the effort and money to produce a roleplaying game that only sold a few hundred copies at best when they could make board games under their other name, Face 2 Face Games, at a fraction of the cost and have sales that numbered in the thousands. They also confirmed it again to me at Gen Con when they said
Arms & Armor v3.5 would be the only 3.5 collection of weapons and armor because they were not going to do a 3.5 version of
From Stone to Steel.

As far as an official notice, don't hold your breath. I doubt any company will make a public announcement saying they are giving up. No one wants to admit defeat and many will probably try to get back in the game if things pick up again.
