Official images of two more Advanced figures - AD-27 Deluxe Bumblebee and AD-28 Snarl.

These are August items, but likely to be after the Aeon store exclusive Wheeljack, which has a release on the 8th of August.

Looks like AD-18 and AD-19 must have been cancelled, as their names or forms were never revealed, and should have been released last month.
