I know they plan on doing like some sort of new shit down here in Florida. A tech told me something but I forgot what it was. Something like live feeds where it takes a while to switch channels. Kinda like EVERY channel on demand always.
Which, interestingly, is not really related to the 3ghz upgrades. As MacLeech noted, the 3ghz upgrades require either a new cablemodem or a new cable box to take advantage of.
My guess is they'll do something like release a big HD lineup utilizing the new space with MPEG-4, and require the customer go get a new box to do it. They can relegate all the old HD DVRs to SD customers. The extra space will be useful for DOCSIS 3 as well. I'll be happy with either one.
