As soon as I found out about Fibe TV, I had an inkling that eventually they would transfer everyone to Fibe from Sat. It just makes more economical sense. No expensive satellites, it'll use the same infrastructure that they're laying for their Internet anyways, it removes the need for PPV channels, since with Fibe TV you can OnDemand which means more room for channels including HD, it's arguably a better television service and experience as well.
Of course, it'll be years if not a decade before they end their Sat service. Last time I checked, Fibe TV won't be in my region until about 3 years, and it's the same for most of Bell's customers. There's no way they'd remove all those customers until they can actually transfer them right over to Fibe TV.
