Looked like they are just trying to see where "the line in the sand is..." or judge how much pain the market will bear.
Have been in some of those pictured places, most recently at DKR-M in Austin, and it adds quite a higher level to the in-venue experience.
From the gripes, moans&groans, et al I've read on various sites, these types of facilities & food services upgrades are what you have been wanting.
But, just like the recently completed AI2020 fund drive, TStan's looking to the ticket buying fan base to tip that delicate balance of "Wants" vs "What I'm willing to spend for what I Want" to stadium upgrades without doing a Dave Braine(less)/DRAD oversell/overdo/overhaul.
Just my $.02 worth.
