So I think Takara-Tomy learned their lesson. For the United line (basically the most current adaptation of the Classics figures in Japan) they decided to release Stepper as a mail-away through their Transformers Generations book. In direct homage to the original, this Stepper uses the Jazz mold and Nebulon is a redeco of the Cyclonus targetmaster Nightstick.
Overall this figure is beautiful, mimicking the original Stepper nicely while keeping a modern aesthetic to it. The gold is very nicely done and not too garish. I was also surprised at the size of the box he came in, it was very minimal and doesn't waste space with any frills.
And of course because the Jazz mold has speakers built in to the mold, Stepper gets them as well, only in Sonic White.
Nebulon is nicely re-decoed from previous versions:

Unfortunately I don't have the original Stepper in order to compare this figure, perhaps I can rectify that situation in the near future :-)
