I didn't attend either, but was at the Lawrence location on Saturday and asked about the Sunday presentation. Apparently there are going be several of them, with batches of invitations being sent out for each, to get as many owners as possible. No criteria mentioned on how they are grouping them.
Presentation included info about the new SC rollout (no dates, just the same update as the website - before the end of 2017. Openings based more on permits and negotiations than actual construction, which I was told can be pretty quick) and the marketing contest to send in the best "ad" from fans. Also reviewed the referral programme and the rewards being offered including Space X visits, a MS P100D, etc.
