I got tickets for my gaming group, but we've never attend this before. We are looking forward to trying out a full run at a game before potentially buying one but my question is this: is there a list of the games available posted somewhere?

I don't think you'll find one. The list is dependent on what the publishers donate, and that's not set in stone until they arrive on-site.
I don't know about a list, but when I tried this a couple years ago when I last attended, I remember there being a good selection of new titles, and I remember there being a few/several copies of each. My group didn't have a problem finding the new titles we wanted to check out.
BGG typically posts the list a week or so before the con begins.
