It's good to finally see the Wheeljack head being released, but a shame that it is a store exclusive in Japan instead of the main Advanced line... which will make it expensive.
According to the Hasbro people at BotCon, they have no plans to bring over / release any of the JP Advanced figures. That could change later, but at this time, don't expect it.
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.
According to TF Source there is a AD31 Ultimate Optimus Prime coming in November. It uses the Leader Optimus Prime mould and features remoulded parts and metallic paint apps. Note that the black and white photos are placeholder images. Here's Seibertron's article on it.
I've pre-ordered that BB. maybe the 18 and 19 are being held off till the movie releases in more parts of the world, to allow for "lack of character Knowledge" going into the movie, maybe they represent someone that doesn't appear in the trailers.
I bought Leader Prime locally the other day, now I'm wondering if I should take him back and pre-order this when it pops up on anime Export.
