For anyone who is interested and missed earlier re-issues, I noticed on BBTS that they have listed a number of G1 Re-reissues for pre-order:

Optimus Prime:

Powermaster Optimus Prime:

http://www.bigbadtoystore.com/bbts/p...26&mode=retail

Ultra Magnus:

Soundwave:

I assume these may all turn up at other vendors soon.
