Got mine, have been playing PDZ, and as well Halo2.
Really enjoy the system, seems to be without any issues so far except for feedback / echos online thru communcation.
Took a while to download maps ffor H2 online play...
Played 3 systems ethernet linked Halo 2 last night... linked new 360 with two original xboxes in my game room, on three tvs...
