Yeah, whatever happened to the DOTM line? Only now is finally Human Alliance Soundwave (the AMG Mercedes) coming out and I have yet to see the Target-exclusive Deluxe Leadfoot around (the TakaraTomy version is fortunately available on eBay, for a price). I do understand why people (ie. collectors) are upset by Hasbro cancelling the TF Prime First Edition toy line; I have to admit I liked the blue cards and boxes more than the white and red RID versions. And with the reported changes you mention, including several figures possibly not being released in the RID line in their original conception, I too would go for TakaraTomy if I had to. I did get hold of most of the First Edition figures, but I'm missing the Deluxe Megatron, Deluxe Vehicon and possibly Deluxe Soundwave (I believe I saw the latter being allegedly released by TakaraTomy, but I have not found one on eBay. Or I missed the window of opportunity). I hope any changes they make to the figures are just purely cosmetic and that it has nothing to do with quality control issues.
PS! The new Transformers Prime: Robots In Disguise packaging looks rather similar to TakaraTomy's striking Transformers United packaging. Could be this is better at capturing the interest of potential buyers (young AND old(er))?
PS (2)! This sight
could perhaps ease our worries on the Cliffjumper situation. Looks very much the same as the First Edition, at least on the outside. Not sure what they mean by "Revealers", but it seems to be the Deluxe size class. The Voyager Megatron has a "Powerizer" sub-name attached to it because of built-in electronic features, so I'm taking a guess (probably could have verified this by googling a bit, but I'm feeling lazy at the moment
