Yeah, Wiki has it at 45k. If anything that would be a really cool stadium as it makes a 45k stadium look like an 80k stadium due to the amazingly steep sloped seats.
I bet it would be an amazing viewing experience in there. Looking at more pictures of it, I'd love something like that for Calgary. Just a spectacular stadium. The last of the three pictures here really illustrates how good a job they did of putting 45k seats as close as possible to the field. In terms of fan closeness, they nailed it. I want this!
