2 GHz Quad Core should be really fast. Currently we have dual core 1 Ghz in Sony TVs and Quad Cores with 1.2 Ghz.
Not to forget the IPC improvement.
Oh and the best feature is probably Gigabit ethernet!! Finally able to play UHD Blurays over network without any buffering issues.
Shame it doesn't have MPEG2 support. Kinda need that for smooth decoding when paired up with a Hdhomerun Prime or Connect. Really not confident on 1080i @ 60fps being decoded in software.
BUT will they be Chromecast-certified?
