The way I understand it, the presentation will be a comprehensive view of the "business plan" for SPZI and, possibly, 141 Capital. This will NOT be a demo of STv2 or SWARM. However, they will be on display ALL DAY at the expo. I'm sure prospective investors will have ample opportunity to get hands on demos of at least STv2. I would think that could possibly loosen up a few purse strings.
I'm also pretty sure that these attendees will have checked out everything that is available about the companies they have an interest in before they ever show up at the expo.
So, not answering for wing, but for myself, I think it's entirely possible that some considerable investment could result from the expo. IMHO
