According to the official Infinity Ward Facebook account, remakes of classic Modern Warfare Shipment and Rust are, indeed, a possibility for future DLC.

Only a few moments ago, Infinity Ward made this statement via their official Facebook account.

We just put in some requests to our MP design team which could lead to some of your most desired updates to Call of Duty: Modern Warfare 3!

Here is what we suggested:

Community Playlist Updates:

Desert eagles in One in the chamber and All or nothing

Change infected weapons

AoN & OIC separated from gun game

Add community playlist leaderboards (aon, infected, dropzone)

Weapons Complaints:

Guns like the M16, Model 1887, PM9, and the MP5 need more love.

Riot Shield:

Does not have master and veteran challenges to carry over prestiges

The hit deflection for the shield, especially on the back.

Other:

Final Stand give the player putting the player in final stand the full kill? (if a teammate finished the second chance player off).
