Quake 4 - Why is it missing from Steam?

[schnipps]

Why is quake 4 not in the steam quake pack, nor in the id pack or even on Steam? Was it made by another developer?

Yeah i thought it must have been something like that, you would think they would put it on steam and do a deal to add it to the quake pack, seems mental that they havent.
