Studio Series 1986 Arcee is out in America, which sounds like a revision wave as it was found with the two newest toys from the last wave (Sideways and Bumblebee).

Also found in America is the wave 2 Legacy Core class (Shockwave, G2 Megatron, Optimus).
I am also thinking that Shockwave was part of a revision wave, as it was only found in JBHifi with Rodimus, but not Megatron or Optimus.
