Comcast needs to move HD to MPEG 4 and that can free up a lot of room / add more HD and down the road get rid of SD channels that are also in HD and put the SD only stuff in MPEG 4 SD. Also maybe some SDV for the part time / overflow feeds.
There are some 1 GHz cable systems (not Comcast) Comcast still has some old 650mhz systems.
