The list of companies sending representatives to iGaming North America is on the website’s home page – and you’ll notice that right now, it’s probably 70-30 favoring the land-based side of things with the tribal gaming interests being well-represented. Traditionally, the i-gaming folks register within the last 2-3 weeks before a conference – no matter how hard we try to get them to register earlier! I’ve been organizing i-gaming conferences since 2000, so I can swear by that maxim 
There are definitely operators in attendance and last year we did have a smattering of affiliates – who are mostly returning this year, so I take that as a good sign that the conference was valuable for them.
I hope that helps answer your questions! Happy to address any others that come to mind.
