Shaw Direct still on in the USA?

We are in Las Vegas and are still getting most of the Hi Def StarChoice channels eg 002,that could be on the third satellite. We know that we will lose these at about San Carlos Mexico , but have always had the standard channel as far South as Mazatlan. (22 Degrees Latitude). I guess April will tell us if Shaw is going to completely abandon the older satellites. Just have to wait and see.
