Hell, looks like they didn't even read my email. Three weeks later, I jsut got this in the email:
Dear Sir/Madam
Thank you for contacting Take 2 Technical Support.
In order to fully troubleshoot the problem that you are having please try
the steps below:
1. Delete all temporary files from your system.
Navigate to C:WindowsTemp and delete all files in this folder.
Navigate to C:Documents and Settings*Your User Name*Local SettingsTemp
and delete all the files in this folder.
You may need to turn on the ability to view hidden files and folders to do
this. To do so, double click My Computer, then click Tools and Options.
Then click View and select the option to view all hidden files.
Then reboot and try the game again.
2. Close down all background tasks.
To do this click Start, then Run, then type MSCONFIG and click OK. From
there click on the tab marked startup.
For Windows XP users click the button marked as Disable All, then click
Apply and Close.
For Non Windows XP users, please remove the ticks from all of the boxes
apart from the below four and then click Apply and close.

your video and sound cards available from the website of the card

Useless garbage tech support. I haven't heard from Firaxis, either, so I assume the official answer on 720p support is "Thanks for the money, sucker."
