Hasbro announced a fan vote on facebook and instagram with two rounds - Perceptor Vs Astrotrain and Thundercracker Vs Skywarp. The winner of those two pairs will then face off to give us the reissue that will come out in the first quarter of 2020 (our Autumn).
Voting seems to be very short and rushed, with just a matter of days for each vote... as if they need to suddenly start production 15 months before it gets released (March-April 2020).
It is also odd to have it appear that there will be just the one reissue, over a year later (maybe there will be others released with this one, and this is just Hasbro's way of making us feel like we have a say in what gets released).
