CoD2 will more than likely have no strafe jumps as the SJ was a bug in the Q3 engine.
CoD2 will not have stacking (like in RTCW/etc)
CoD2 I doubt will have precise tac nades, as I have a feeling the nades will be thrown slightly different each time.
Also, the mappers are still using a similar raidant (radiant = mapper tool) and I can guarentee the map bugs (like un-clipped walls, will be hard to find).
Its not looking good on the jumping front
