Xbox 360 Arcade dropping to $199 on September 7?

We've been hearing whispers that an Xbox 360 price cut is in the works, and now we're starting to see some evidence -- VGChartz scored this image of an unknown retailer's inventory system showing the 360 Arcade dropping to $199 on September 7th. There's no word on whether the rumored 60GB and Elite price cuts are coming as well, but they'd certainly be welcome -- and with Rock Band 2 scheduled to hit just a week later, we'd say next month is looking like a good one for Xbox fans.
