Yea, I guess thats a posibility.
I did hear about DVB-C2 being rolled out this summer.
For those of you unaware what DVB-C2 does, heres a basic synopsis:
DVB-C2 will provide higher transmission efficiency while remaining fully interoperable with other DVB-systems. (Im assuming that means the V+ will be fine.)
The 4th Q of 2007 Results are expected around the 28th Feb. and that will have more details on the DOCSIS 3.0 Roll Out, and ultimatly, the DVB-C2 also.
