The final JP MP Convoy/Optimus toy

Apparently, TakaraTomy are retiring the Masterpiece Optimus/Convoy mould, with one last release - MP-1L.

Probably very minor deco changes, like they did between MP1 and MP4, but the difference will be a sound-base will be added, which the Hasbro DVD Anniversary version had (and the JP 2010 Mail-away promotion).
It is said that the sound-base will have a message from the original Gen1 Convoy voice-actor (Genda Tessho) to announce the next Masterpiece figure.
Since this version has a tentative release date of March 2011 (two months after MP Rodimus), it should be revealing a brand new Masterpiece toy. (bring on Galvatron!!!)

On a side note - another production run of MP-5 Megatrons is coming soon as well, for those who haven't yet got one or don't want to pay hefty 2nd-hand pricing.

Fingers crossed TT decide to spend a little extra on this release and give us a Roller... to complete the 'set' of robot, trailer and roller. (doesn't sound like it though)
(also just read on tfw2005 - if this retires the mould, we won't be seeing an Ultra Magus with trailer :( - would have been expensive, but would look good with Rodimus and Galvatron if we get one)
