Wizard220, a staff member at Infinity Ward Nation, confirms why the CoD2 patch has been delayed for the PC:

Activison and IW have an agreement with MS to roll out any patches for COD2 together - for both the 360 and the PC. As the 360 was shipped without an adequate update system in place, this has held things up - until an adequate update system for the 360 was implimented.

Gotta love this bullshit corporate strategy! The drama around CoD2 and the growing legions of dissatisfied players has taken a toll over at IWNation, where respected moderator Tally has been ‘fired‘. The announcement was made shortly after he revealed some details on the upcoming patch:

Ok, here is a run down: #Server-side only capabilty #Increased gamestate - how much? Well, in an email to me by a Dev, it was stated: #Extra server cvars to turn things on and off - i.e. all the ‘idiot hints’ (or ‘noob hints’ whichever you prefer). #New gametype - not sure on this, but Im lead to belive its Retrival. #Recoil on a lot of the weapons - MP44 and Garand for sure, which other ones Im not sure of. #Fixes for all the known map exploits #Option to have alternative health system than regeneration.
