I think it would be an enormous mistake having the 40th anniversary tribute as the opening panel to celebration without some sort of big surprise or announcement at the end. 2015 they ended it with a TFA trailer. 2016 they made an effort to end with a bang with that bts reel for R1 (though that was kind of lame). They love kicking off celebration with a bang. Since they moved the Episode 8 panel in favor of starting with the 40th anniversary tribute, I’d be shocked if they didn’t have SOMETHING big planned, even if it’s not what we’re all hoping.
