So far there's been no announcement but highly unlikely... they're part of the United line only I reckon since Hasbro has already released the mold before.
The Voyager Megatron was released by Hasbro (in a vastly different colour scheme) in 2006 Classics RID range.
The Prime has seen two releases already by Hasbro, the first time was in the 2006 Classics RID range and then again in 2008/2009 Universe range.
Edit: Having said that though, it appears that United Bumblebee will be getting a release in Wave 2 of RTS even though it's been released by Hasbro before on two occasions (Classics RID and Movie Legacy of Bumblebee 3-Pack) so I guess anything's possible.![]()
