I think there's a crapload of blue sky right now and at the end of the day the timelines for these attractions are gonna slow down dramatically. I agree there are currently plans to knock down that theater - I don't think it's going to happen within the next three to four years.
Remember - all it takes is for one of these projects to underperform. Then Comcast rethinks its aggressive investments/expansion. I hope it doesn't happen... but it could.
Time will tell, obviously.
