TF2 SDK release is sick

Finally remembered my password, yahoo.
Anyways, in typical valve fashion, with little fanfare on a random Tuesday night valve dropped the TF2 SDK and opened the ability for TF2 source mods to be listed on steam legally. This is sick! TF2C, Open Fortress, and other mods don't have to work with old leaked resources anymore. I can't wait for TF2C to be rebased and release on steam with all of the SDK's bugfixes and modernized code.
