The $199 Xbox 360 price cut rumor we reported on yesterday got a little more real today after a screenshot surfaced showing the updated SKU for the Arcade model. VGChartz got the scoop, and noticed that the September 7 release date for the updated SKU coincides with some other big Xbox 360 events: the launches of Square Enix's Infinite Undiscovery and Rock Band 2. Both titles are Xbox 360 exclusives around the price drop time frame (although as Kotaku notes, Rock Band 2 comes out for other systems in November).
