The Shattered Glass Universe isn't just "evil G1". It's since expanded with other characters like Demolishor. If there's only ONE A3 in all of G1, RiD, AEC, Shattered, Animated, Movie, and Prime, then why is he evil in Shattered?
^Yeah, also if your a a completest, then 13 molds would be right up their alley. Some Primes may appeal, some won't- it's that simple!
This. Has/Tak is going to think it's finacial unfesible to release 13 new molds. They're going to create a mold and reissue with a new paint job 13 times.
I don't think we will see them all at once. Hasbro didn't want to release all the Constructicons from ROTF because they didn't want the shelves clogged up with construction vehicles. I think, if they continue to do Generations lines, they might start releasing them at larger size classes (assuming they start doing a voyager or ultra class). I think Megatronus/Fallen and Zeta/Sentinal Prime would be a good wave together as they will be current in our minds due to ROTF and WFC.
What about Logos Prime/Cybertron Soundblaster (Soundblaster (Cybertron - Transformers Wiki)) is he still considered one of the first 13?
The problem isn't that he's evil in SG. It's within the realm of possibility that he has personality altered by the effects of that 'verse (like, the fact that Transformers in there run on Embers rather than Sparks). The problem is that the SG Version of him is ALSO evil in the Transtech 'verse. It COULD be that the SG guy is not really A3, but some guy using his name for the reputation it carries (the way BW Megatron does), but, there's no canon basis for that.
