From Joystiq:

The gaming community really throws the word “limited” around with little thought of its meaning. Walk down the Xbox 360 aisle of any GameStop — there’s more Halo 3 Limited Collector’s Editions than there are stars in the sky. However, it sounds like Infinity Ward’s upcoming blockbuster Call of Duty: Modern Warfare 2 will have a limited edition worthy of the adjective — no additional copies of the Prestige Edition of the game will be made following the title’s release.

Activision is so serious about keeping this edition to a limited run, it is denying requests from retailers to create more.

“We’ve already been asked by retailers to up the production numbers due to demand, which we immediately denied,” Community Manager Robert Bowling told IGN in an interview].

Nice to see a retailer stick to its guns and allow an extremely marketable special edition to stay special (much to the chagrin of ATVI shareholders).
