The game valve is going to announce at gamescom has been leaked by testers (and a cheeky valve employe^^)
According to tester here are a few details
+Air movement feels identical to CS: Source
+Ladder movement feels the same as CS:S
+Test servers are running tickrate33, so bunny hopping was inconsistent (presumably will be changed)
+1-shot kills with any weapon other than Desert Eagle currently too difficult to achieve
+Flashes are similar to 1.6; Smoke grenades similar to CS:S
+ Planned to be released Q1 2012
+ Focuses on 5v5 competition
+ Press release within 24 hours from VALVe
+ Plays on an updated source engine
+ Individual & Team rankings
+ New Guns added
+ New Grenades
+ Dust & Aztec major revamp
+ Spamming still viable
+ Ammo is free
