The official release date is actually tomorrow, but these have already been found today.
There are a couple more Arms Micron figures - Wheeljack & Dreadwing, each with a new Micron mould.
Plus a couple more EZ figures - Optimus Maximus & Cmdr Skyquake.

But the big one people will be excitedly looking out for in their mailboxes - Masterpiece Lambor (Sideswipe).
(then it's another two month wait for MP Soundwave)
