Theforce.net is reporting that the latest UK PC Zone magazine has Star Wars: Empire at War (the new RTS developed by much of the old Command & Conquer team at Pteroglyph Games) as the cover story. Readers are reporting "This new PC game is set two years before ANH with a certain amount of cross over from Episode 3. It appears to include ground battles set in desert and greenland areas with attacking AT-AT's and a new Imperial ground based vehicle called "TIE Crawlers"... The action also takes place in space with rebel fleets taking on Star Destroyers".
By the looks of the magazine scan, it's scheduled for an Autumn 05 release.
