Might even be legal reasons. I am not familiar with Japanese rules and regulations regarding pre-order goodies. And Due to brand unification I say it is unlikely Takara would not go in on it. Also the idea someone put forward that Takara is okay with just the MP Starsaber is laughable. How many MP Optimus prime figures are there now?... Unless MP Starsaber was underperforming, that could be the only valid reason.
