Kudos to Butcher, who pointed out this little tidbit in a 3D GPU article:

Which developers [will be incorporating the GeForce 256 features (T&L, etc.) in upcoming games]?

The developers which are out in the open are (in alphabetical order) Acclaim, Bungie, Computer Artworks, Gas Powered Games, id, Rage, Sierra Studios, The Whole Experience. There are numerous others planning early DX7 T&L titles but until they make their own public statements it would be improper for me to name names. But make no mistake, this is going to be a T&L Christmas!

The GeForce256 chipset is a remarkably potent one, and it's good to see that Bungie is making use of it. Still, by the time Halo is released, who knows what else is going to be out there?
