Pinnacle Venue

Anyone have any insight to what the Pinnacle venue is going to be like? I've seen a couple of Tennessean articles more recently, but they're behind the paywall, of course. Looked for interior renderings but didn't see anything from a quick Google search.

So far all I've gathered is:
- 2x seating capacity of the Ryman (I've seen 4,500 and 5,000 stated for its capacity vs. ~2,300 for Ryman)
- Some shows have GA in the lower section, some have assigned seats

Thanks!
