For those who don't know whats come outa X05 yet, go here http://xbox360.ign.com/articles/655/655291p1.html
Thats alot of stuff. Note that the direct feed videos although they say insider can be streamed with the watch now button.
I highly reccomend PGR3, PD0, Too Human, and Kameo just for starters ;)
PLEASE do not vote if you havent actually bothered looking at things properly from X05. Don't complain about PDZ looking horrible going by the first X05 PDZ video (which sucked admittedly) without looking at the new vids
