at Microsoft's E3 press conference by iFixit showed some surprising non-changes to the redesigned system. Namely, the console still uses the storage, cooling fan and processing power from the current version of the system first announced in June 2010.
Among the changes made to the system (referred to as the Xbox 360 E), iFixit noticed that Microsoft updated the RF module and that "the absence of the power button backlight found in the Xbox 360 S is easily noticed." The redesigned console is available now for the same price as the existing models. We got a good look at the system ourselves at E3, albeit from the outside.
