To be pedantic, Tomahawk is the original with DotM Vortex as the pretool
Seriously though, the GDO vs. Generations Springer leads me to believe that Hasbro Asia develops independently
of Hasbro US as they are, legally speaking, two separate companies under the Hasbro umbrella name. Hasbro proper may have authorized Asia to develop the GDO series, without anticipating the future demand for the US at all. Let's hope they learned a lesson from that, and let's thank them for listening to us
As for Springer, I still plan on getting both the Triple Changer and the GDO one, blame my love of repaints. Thing is, Springer (and Wheelie by extension) went above and beyond with not just the new head, but also his new weapon. The Triple Changer will go with the regular display with Rodimus, Kup and Blurr, while the GDO one will go on the Expanded Universe shelf.
Yes, I plan ahead.
