What is tf2?
The wiki page for tf2 doesn't give any obvious indication that tf2 is experimental, though I can imply that by the fact that it's in the geometry_experimental stack. Regardless, I'm curious about how tf2 differs from tf, how far along in the development process it is, if it is targeted to replace tf at some point and if so when, etc.
EDIT: Another relevant page, though it doesn't quite answer the questions I have.
