At this time, nobody is sure when F2 is going to fall out of the sky (it has no fuel to maintain its orbit. It's not going to fall, just drift too far off station for a fixed dish to pick it up).
We had F2 in Florida all last winter. It's possible it will last this winter coming too. It's also possible it won't last - nobody knows. Shaw has another satellite G1 that will provide coverage in Canada and northern USA for the next few years.
Vegas will be the same as Florida. If someone is saying they can't get Shaw Direct in Vegas RIGHT NOW, they're wrong.
