Telus Optic cable will be available for using it as a receiver for 360 starting tomorrow. They are bringing out a deal where if you get a package you get a free 200 dollar Xbox 360 console. This is a Canadian Cable company from what I know. It might not even be brought up at E3 but still news all the same.
More features/games/programs for Xbox 360 will be a great add-on, I honestly hope they won't announce that there'll be a new Xbox 'cause 360 is fine as it is, does everything (even Blu-rays, BD 1:1 backups from PC to 360). Nintendo will be announcing their new console, but I see no point of buying it, PS3 and X360 do it all perfectly.
