There is a picture on this page of a robotic silhouette similar to that of a mechanical Mickey Mouse, and a logo next to it showing what can best be described as a G2 Autobot logo that has been Mickey-ized, for lack of a better term.
You can see the original thread here, which includes a scan of both the silhouette and the new mixed faction symbol.
No word yet on how extensive this will be, or on exact details at this point.
