I also don't think that much more can be done for Henkei Jetfire.

It is a rare thing but Hasbro did an excellent job with Classics Jetfire so I don't know what more can be done to improve it. They can add chrome but that would go against the original color scheme of the character unless its subtle but that won't be much of a change.

I am also interested to see if the Classics Hot Rod will have any defining improvements.

Mostly though I am looking forward to Henkei releases of the Universe molds, they will rock!
