I wonder if this as a result of their investigations into ADSL over NTL copper?
From what I understood, ADSL gives NTL more chance of delivering high speeds as they can fit equipment very close to the customer and the technology is cheaper (and not subject to the same noise hassles that coax has).
I can't see the coax system managing to keep a stable connection for 10Mbps (it could never deliver a stable connection even at 1Mbps for me).
Anyway, "coming soon" I suspect will be the order of the day here
