New Xbox 360 gets official at $299.

According to a Microsoft representative, the Xbox 360 Original will still be sold while there's stock, but they're not making any more of them. Once they're gone, they're gone -- and we'd assume a new $199 variant of the new design will eventually be released to fill the void.
