Infinity say it'll "eventually be coming out" as an arcade title on both the next-gen consoles as a stand-alone, but price and date "are unknown at this point." It will have multiplayer.
"Prestige and Hardened Edition buyers will be getting access to Call of Duty: Classic first. It'll eventually be coming out for both Xbox Live Arcade and PSN as a stand-alone arcade game," said community manager guy, Robert Bowling.
"However, price and release date are unknown at this point. It's the true original Call of Duty including full multiplayer," he continued.
Call of Duty: Modern Warfare 2 is being released on Xbox 360, PS3 and PC this November 10th. The pricey Prestige Edition comes with real Night Vision Goggles, and other goodies.
