We have seen the Henkei Jetfire by Takara and very much the usual sale strategy, Hasbro will have their own version using the same mold. You will be able to see some of the differences when I put the two next to each other. Even though the colour scheme remain very much the same, the artwork differ. Henkei Jetfire has chrome verniers while Classic Jetfire's verniers remained black. Classic Jetfire has a bigger area of cockpit exposed, colors of the missiles are translucent blue and in order to revive the shield, it has the rub on autobots label which is absence in Henkei Jetfire. The last difference I noticed is the colour on their head visor.
I have friends who told in terms of plastic quality, Hasbro version tends to lose out to Takara. I guess this is rather subjective and there's always beauty in either versions. As for some, they are just happy to have more variants to boost the collection. These two are not all and I will showcase more variants of this Jetfire courtesy of Jason.
