Sembra che il tanto famigerato upscaling del 360 non venga effettuato da (H)ANA, che sarebbe un semplice chip di video output, ma dallo stesso Xenos

The only other major change under the bonnet is the new HANA video display chip, replacing the old ANA version in the classic 360. This chip has erroneously been described as the silicon that deals with the 360's inbuilt hardware scaling. In truth, Microsoft has now confirmed to us that it's merely a video output chip - a means of transferring the framebuffer into all of the different signals: composite, s-video, RGB SCART, component, VGA and - the key addition with HANA - HDMI. Scaling itself is actually performed by the Xenos GPU (most likely using a variation of Lanczos resizing) so in that respect the Elite performs identically to the original Xbox 360. The presence of HANA confirms that there will be no aftermarket HDMI solution for the current model.
