So with everything being said currently, it seems as though that they will be building a multi-sport stadium that will be able to accommodate different usages of sports. That's a very reasonable choice as we can only expect the Stampeders to play at home at least 10 times a year and it doesn't make sense that they have they're own stadium. Having the multi-sport field-house can accommodate many uses such as, concerts, soccer, etc. UNLV is proposing a stadium that I think will be similar to what Calgary is looking for. That stadium can house different sports/events and as well be used indoor/outdoor.
The new motto for the project is Live | Work | Play

"LIVE"
"WORK" May be their to have some mixed use offices as well as a place where people work in the entertainment district.
"PLAY" of course means where we can expect the teams to play
I would love to see somthing like what they are doing in Orlando with the entertainment district and combine that with L.A Live. It may be ambitious but the buildings could be similar to what we see in Las Vegas CityCentre:
