According to recent trademark application by Hasbro, the classic style of logo with the name split in half (Trans above Formers) is being re-acquired.


Apart from the recent usage on the handful of Gen1 reissues, I don't think it has been used on their regular packaging since the 2014 Generations toys, when Hasbro started using the vertical, one-word logo on the packaging... so maybe they are about to start using it again on their main lines again.
(if they are currently using it on the Gen1 reissues, I don't know why they need to apply for it, as they should already have the trademark... as this doesn't look like a renewal)
