Nope. Last I heard they only said where they would be! I do think I heard something maybe end of 21 for the one in Austin. I can't remember where I read that though. I figured first one be Augustish?! I mean they provide the broncos so not like we gotta wait for ours! Again I'm just guestimating!
I'm not sure how they plan to vet who can attend. I know the cost is baked into the purchase price. And a buyer can pay an additional fee for guests. But attendance should be limited to those that actually purchase and take delivery.
