The only thing retooled on Smokescreen from Knock Out is a spoiler. His head I thought was retooled...then I took a closer look.
Heh. Doesn't phase me, as I have a couple of reasons not to get "Arms Micron" Smokescreen. Such as the fact that while he is a great character in the series, he just does not feel like he belongs in my collection. That, and his Arms Micron partner does not appeal to me.
Besides, I think once I preorder Wildrider, I will be good for a long while when it comes to the Arms Micron line.
