Japan have indeed done a few obscure reissues in recent years, from the late 90s to early 00s, so the Unicron Trilogy probably isn't out of the question... but GEN Selects in Japan has been contemporary moulds, so maybe it is a toy that homages Cybertron Galvatron and someone put in place-holder info that they googled.
Maybe the next chapter after this revisit of the Beast era is homages to the Unicron Trilogy era (Armada, Energon, Cybertron). I think with Generations, the next "big" era to homage would be that one, as Beast Machines was one of the least popular series to Transformers fans (back then, and now), while RID/Car Robots was mostly a mix-n-match of existing toys, leaving only a small number of new moulds (only about 12) to homage (probably not enough to use as the foundation of a whole new chapter).
Combiner Wars - includes homages to mostly 1985-86 (combiners)
Titans Return - includes homages to mostly 1987-88 (headmasters & targetmasters)
Power of the Primes - some homages to 1988 (pretenders)
Siege & Earthrise - includes homages to 1989-90 (micromasters)
Kingdom - includes homages to 1986 and 1996 (Movie and Beast Wars)
(I have to be careful with my guesses, in case I get something correct and someone at Hasbro thinks I am leaking info from one of my sources, even though I didn't actually get any info.)
