This is a possibilty but by no means a certainty, TV Cabo are not so cash rich as Digital + and the other big providers, they only just changed to ROM10 about 1 year ago and I personally don't believe that they could afford another card change so soon.
Obviously they will test the system but my belief is that they will move to mecm like Polsat before they go to this new system.
This system is currently being released by echostar dish network in the US so very soon we will no how easy it is to compromise.
