Hot Toys has announced [and teased] that might possibly be viewable at the Sideshow Collectibles San Diego Comic Con booth. Those announcements (all 1/6th scale, I'm presuming) include the Grand Moff Tarkin teaser shown above. For Star Wars fans, I believe this would be the first time we've seen Tarkin in high-end 1/6th scale.

Also, as seen below, they've announced the Valerian 1/6th scale license and are showing off a pair of figures based on characters I have no clue about.

There's the announcement of the Thor Ragnarok license, though that's not much of a surprise based on Hot Toys' 1/6th scale Marvel series. 

Finally, they're showing off a teaser image of the upcoming 1/6th scale Yondu figure from Guardians of the Galaxy Vol. 2.
