Games always have a limited shelf life, its only natural. All game start off massive and then dwindle.
By 'dead' I assume you mean dead with clans not playing it so much I am sure you are right.
I dont think COD4 will die off as a game though so long as it offers something different. Rainbow 6 and Warhawk were quite different from COD3 so inevitably took some of its players.
I actually think COD
3 will still be going reasonably strong by next March as well! its a great online game and a few thousand less active players will make for great servers again! I wont be selling it. Sure, its dying for clans now but some clans will still be playing it through the New Year and if COD4 is crap then they'll be back..
