You have to squint, but user @maro254 posted a bunch of advance looks at HasCon on Twitter.  Of note was a post showing the Star Wars area with some newness - you can make out the 3 3/4-inch Vintage Hover Tank, a bunch of cardbacks, and what appears to be a 3 3/4-inch vintage Snoke!  Take a look - and we'll have more later.

Here's the Star Wars booth. #WotCStaff pic.twitter.com/fFZz8Z2ZRe
