The Age of Empires III Forums has word on plans for the version 1.02 patch for the RTS sequel, while this thread offers an additional note (thanks Keith). Here are both posts:

We have been hard at work getting ESO up to speed for all of our fans. We apologize for any inconvenience you have had while we work on the servers. Our team has been hard at work on a new patch and we will have it for you in the near future. We are looking at

-Hardware Compatibility Issues
-Sound Stuttering Issues
-Fixes for Direct3D
-Stability and Crash Issues
-Hotkey Editor

We will post more information in the Game Updates section soon.

We have many more fixes than what is listed here an a few extra surprises for you too.

[SOLUS]

Also see this thread about another hopeful addition. (paragon)

Here's the post mentioned from that other thread:

I think this might be missed in the patch notes, but we are attempting to have a set of 5 large maps make it in to patch 1.02. As long as the sky doesn't collapse on them, they are versions of maps already present, except bigger :)
