They aren't releasing a list until they've notified the employees, but the seven stores will be closing Monday, then reopening Wednesday to start clearances.
Last Circuit City clearance I went to was a complete bust-- all software was returned to the respective companies and there was no gaming merch anywhere.
Still, you might get a deal on a TV or PC supplies.
The one that closed by me during the last mass closing reopened before Xmas as a "CC Warehouse Store". I never been back but am told that it's just display models and odds and ends for sale. No gaming goodness.
