I received my 622 yesterday and now subscribe to a DishHD metalic pak. I must say that I watched quite a bit of the Gamplay channel. It was very interesting even though I gave up PC gaming before my daughter was born (haven't played since 2000). Anyway, I plan on buying a PS3 (mostly for the Blu-Ray player) but, since my daughter it now four, I can teach help her develop her hand and eye coordination playing games on the PS3.
Just as long as GamePlay continues to provide hints, tips, and tricks for all the new games....and perhaps host/broadcast online tournaments with VOOMers, then I'm all for the Gameplay channel. World Cinema was a welcome addition to VOOM15...and FamilyRoom to a lesser extent. IMO, I loved the old Cinema10 format. Until all VOOM21 channels are rolled-out, GuyTV should replace KungFu on VOOM10. KungFu can be moved to VOOM15 (DishHD) or the programming can simply rolled into GuyTV.
That's my 2 cents.
