The cards have been ready since May 2005, and we saw one at E3 2005 but apart from a few demos there was no single game that was using this very interesting piece of hardware.
It's very hard to bring the card to the market and expect to change the world without content.
AGEIA managed to convince game developers to use its marchitecture but it sure takes time for people to finish up its projects. Software developers and especially game developers are known for project delays - we understand them as it's very hard to make a game.
You can forget about these cards before Yule it will most likely be February, if not later, but the company remains quiet about any future plans. ยต
