I'm sure these have been mentioned before, but I only just realised that there were two sets of the Sons of Cybertron 2010 promo toys from TakaraTomy. One is the Animated pair of Optimus and Rodimus, and the the other is the Classics pair.

The 2010 TT promo product lineup.
(looks like another two slots have been added to this 'limited' series)

Animated pair will be released in July, as a general release.
Classics pair will be released in August, through a JP convention.

People have noted that the Convoy figure has been renamed Optimus Prime - perhaps TT are slowly converting the existing 'Convoy' name on re-released toys, to Optimus Prime to match up with the current Movie and Animated versions.
Some translated info here.
