With the backpack hidden away in the box...
I think the Earthrise ones would still be shelfwarming when that one comes out... and in America, the Arcee in Kingdom packaging would be $3 more than the exact same Arcee toy in the Earthrise packaging.

Another 2 leaked toys on youtube - SS86 Blurr, with some screenshots here, and SS86 Grimlock with Wheelie, with some screenshots here.
The mini Core class Optimus toy from Kingdom.
Not sure if this is a leaked review or if Hasbro is giving out more of their unreleased toys for fans to review.
