Yes, F2 is 17 years into its 15 year life forecast. It was expected to last until 2025 but it's using fuel faster than expected and will probably only last until the end of this year.
Once F2 is gone the only sat. Shaw Direct will have is G1 which is aimed at Canada - no Shaw Direct channels will be available in southern USA. (unless Shaw can scrounge another sat. that covers USA) but I seriously doubt that they're even going to attempt that.
Most recent development is that they're transferring channels to G1 but using a new compression algorithm to make all the channels fit. Unfortunately the 6XX series of receivers will not handle the new compression algorithm. I managed to swap one of my (owned) 630 PVRs for a rent free 830 PVR. It will handle the new compression but when F2 is gone, Shaw Direct is gone down south.
I dunno what we're going to do for TV after that. Maybe VPN? Maybe stop travelling? There's no good solution for snowbirds.
