I imagine materials would need a lot of work, the game has hundreds of vmt's. I'd guess models are a fairly easy recompile, but there's also hundreds of those.
I'm not sure why they'd attempt a straight port, even though the new tools have a vmf import it's still probably going to require a lot of rebuilding to get everything working the right way.

I guess my thinking is if they're going to burn all that energy, why not just make a TF3 or TF2.5? Delete the crux, keep the stuff people love, and give it a fresh start.
At the moment the tools require a 64-bit version of Windows and a Direct3D 11 compatible GPU.
Yes, the snips I've seen so far show some pretty significant changes. Here's an example of a vmat file, which is the replacement for vmt:

There's definitely some similarities taken from vmt files, but all the variable names and parameters have changed.
Ooh, layers with separate shaders. I wonder if this "layer" system is how they're going to handle overlays in the future, so that they don't have to float .1 HU above the surface anymore.
