With all of the good news on a completely new Xbox 360 redesign, extra tidbits of information are coming out. For starters, the Arcade and Pro models will be seeing a price cut. The new prices are situated at $149 for the Arcade model and $249 for the Pro model, and both will be discontinued after they are sold out.
Additionally, a second new model Xbox 360 with a $199 price tag will be introduced, but Microsoft hasn't shared details on this new SKU just yet. This price cut announcement will ensure that older models are phased out as several design features, including the power supply and the hard drive, will not be compatible with the new model.
