Waldo of Day of Defeat Source has posted some intersting news in the Steam Forums :

"That's a pretty good assessment Sikari, so I just quoted your post. Most of us put in time on HL2, CS:Source and Half-Life:Source before shifting back to DoD:Source, so that did slow things down a bit. But we're working full speed ahead on it now (and have been for a while). Patience DoD fans. Patience. It's gonna be nice IMO. Quite nice. And no, it's not just a straight port."
