The only thing I can think of is that they want to pull elements from everything, so they nod to everyone around the table, trying to cater to every facet of the Multi-Versed TF Franchise:
1.) Such as, give G1'ers the core characteristics/personas for each Autobot and probably a couple Decepticons (Megatron & Starscream).
2.) Update the Alt Modes and use them to bridge as many storylines/universes as possible...Ironhide a truck, Prime still being a Semi, Jazz a cool sportscar, and Starscream still a Fighter Jet.
3.) Make a story that combine elements from multiple storylines; "Energon Cube" being a new form of the Creation Matrix, Megatron being captured by humans, Decepticons looking for multiple things, Autobots trying to hide and yet still protect humanity when possible, and Transformers fighting the military in multiple conflicts.
4.) Give a visual look that is new and unique, yet still could be used as a Transformers look, like a combo of multiple looks. In a lot of ways this new TF look feels like Trans-Tech (the cancelled sequel to Beast Machines in which G1 and BM were going to come together with Optimus Prime, Jazz, Starscream, and Soundwave working with/fighting characters like Cheetor, Silverbolt[bw/bm], and Tankor).
