Noteworthy details from the stream:
Complete Superion is shown off with all four Aerialbot limbs. Mark keeps using the term "Scramble City", saying "you could probably do some Scramble City with the Menasor model", which is a bit confusing since "Scramble City" refers to not just the ability to swap arms with arms and legs with legs, but mainly to the ability to swap arms and legs with
each other (which I doubt Superion will be able to do since Menasor couldn't).
Mark considers Venin to be the "true leader" of the Insecticons, not Kickback.
Mark pointedly likens Micronus Prime's exosuit to a Pretender shell play pattern, as if to hint that this figure could be testing the waters for how to bring back proper Pretenders. He also mispronounces "Chimera" as "Chy-mera" rather than "Ky-mera". The exosuit is also built like a Weaponizer, so its limbs can detach to become weapons for other figures to wield. The suit's legs become the unicycle's wheel, and it actually does roll.
The Covenant of Primus that comes with Alpha Trion has actual turning pages with some Cybertronian text printed on them. Alpha Trion's altmode is based on a concept sketch for an altmode that was never used before.
Flatline has a new fist on his left wrist where Red Alert originally had only his arm tool.
When discussing Onyx Prime's Tryptich Mask spear, Mark says that all of the Primes' artifacts have a specific purpose for when all thirteen of the artifacts are brought together.
As expected, the Sandstorm Vs. Slugslinger two-pack is an Amazon exclusive. Nate calls him "Handsome Face Sandstorm". Mark is a fan of Battle Masks, so that's why they did the toy-accurate face first. Sandstorm's colors are more animation accurate. Mark says Slugslinger's colors are meant to be a midway between the cartoon colors from "The Rebirth" and the colors of the Takara version of the toy (presumably the Transformers Legends version that used colors based on The Headmasters cartoon).
When showing off the Selects G2 Dinobots 2-pack, they state outright that the next two G2 Dinobots are coming next year.
The Studio Series Decepticon pack is an Amazon exclusive.
