9800 Pro's, some 6800GT's and some 6800 Ultra's.
Have you completed at least 70% of the models?This is hard to say, as a model can be anything from a prop (like a chair, microwave, etc) to the tons and tons of models that go into the levels as architecture to flesh out a level.
A ton is done. We have hundreds of props that you can place in the world, and the artists just continue to pump stuff out.
Are a majority of your models textured?We complete them as they go in, so the ones that are done, are in.
Have all the weapons been programed in and are usable in-game right now?Yes. In, with animations, sound pa , and final textures. We'll probably add a couple more as we go, and there are some whacky ideas we want to explore, but all the base guns are in and we could ship with what we have.Coming "When it's done" from 3D Realms for the PC.
