As reported here, G1 versions of Ironhide and Prowl Mighty Muggs appeared for sale on a chinese auction site, Taobao.
Currently no information on the release status of these two, so we may or may not see them in the future.

Wave 3 Mighty Muggs - Jazz, Shockwave and the movie versions of Optimus and Bumblebee - were on display at SDCC this year, but as yet remain unreleased.

You know I'm looking forward to this.


Also: Prowl's face. Ahaha!
