TF War for Cybertron - Optimus Prime: Toy vs Show

[underbelly]

Hi guys,

New member here but huge TF G1/RID/BW from back in the days! I started watching the TF War for Cybertron series (Seige & Earthrise, can't wait for Kingdom!)

I've watched a few toy reviews and it seems Earth Rise/Kingdom figure of Prime i.e. G1 style 'earth looking truck' is highly regarded. I wanted to buy him but I have a rule where I only purchase figures if they appear on the show; so am a little confused as I thought the toys/figures are based on their show depiction. However this doesn't seem to be the case? i.e.:

Seige:
- Optimus Prime toy looks like his show depiction e.g. both are Cybertronian-style trucks

Earth Rise:
- Optimus Prime toy does NOT look like his show depiction. Toy is a G1 style 'earth looking truck' with trailer, while on the show he looks exactly as per his Seige appearance (Cybertronian truck)

So my questions are:
1. Why does Earth Rise Prime toy completely differ from his Earth Rise appearance?
2. As Kingdom Prime toy is the same as Earth Rise Prime toy, does this mean we may see this version e.g. G1 style 'earth looking truck' with trailer on the Kingdom TV show?

Like I said above, I want to buy the Earth Rise/Kingdom Prime but I was hoping he would appear in the TV show like his toy.

Cheers
