Nokia Removes Carrier Operating Frequencies from New Lumias

I just went to the Nokia website to see if there were any glimmers of hope that the Lumia 920 or 820 would work on T-mobile's network here in the US. When I looked at the spec sheet I noticed that the operating frequencies that were posted there when the phone first launched, were now gone. I suspect Nokia did this because no official announcements have been made as to which carrier will carry these two phones.

Is there any hope that a 920 will hit T-Mobile USA and not just At&t or Verizon?

Could this mean that other carriers will be able to support this WP8 Flagship?

My instinct tells me the 820 is highly probable for T-Mobile, but is this all just wishful thinking?
