These are our very first looks at not just the toys but also the characters, who were not highlighted in the first trailer. There were supposed leaks regarding these character designs and these toys support them with Nightbird's head looking like her G1 self and Wheeljack having a redesign from the Bumblebee movie design to have large glasses and no large "ears" (which could have been guessed from the back view we got from the trailer).
People have asked why this Wheeljack has more of that typical "nerd" look and this might be further proof that Michael Bay has a more hands on role, similar to the one he had in the Ninja Turtles movie, a movie where we know he dictated several looks. This looks very similar to Donatello from that film, where Michael Bay does like having obvious visual cues to reinforce a personality or trait. It's easier when handling a movie with a ton of characters, like this one where we have 3 main factions (and 2 lesser ones). These are just assumptions and guesses, meant to provide possible reasons for this change.
To answer another question, here are all the toys which will get a deluxe release in the mainline independently of their release in the Studio Series line:
Tra Mv7 Core Boy Deluxe Class Ast with the EAN: 5010993983308
Deluxe Bumblebee (Codename: George)
Deluxe Mirage (Codename: Pluto)
Deluxe Wheeljack (Codename: Barcelona)
Deluxe Airazor (Codename: Titan)
Deluxe Nightbird (Codename: Outlaw)
Of those we have now seen Airazor, Wheeljack and Nightbird.
