I saw these on amiami the other day, and since they've been posted up on Seibertron, I thought I'd mention it here as well.

These are non-transformable (like RPMs/Speedstars) but look to be a little bigger... and Bumblebee has doors that open.
The Bumblebee could even be the same one that is packed in with non-transformable Starscream figures that are also being released in Japan soon.
