I agree, i want to see the whole 84 cast in cybertronian modes. In terms of part 3 being Unicron, i kinda hope its not because i came up with an idea for how they could do it. Prime wars trilogy lasted 3 years and if this trilogy lasts the same amount than it will last 2019-2022. That means that 2023 could be the start of a new trilogy. It also is the 10th anniversary of armada so heres what i think they could do: Hasbro could start a new "unicron trilogy" but based off G1 where unicron has arrived and the autobots and decepticons team up to face him and his heralds. While the characters are still G1 they acquire new forms to combat the heralds and these forms just happen to look like a combination of G1 and armada designs. As for a linewide gimmick, the minicons who originally helped the thirteen combat unicron years ago, have returned to battle the chaos bringer once again and powerlink with the bigger bots to bestow upon them weapons from primus himself who is revealed to be cybertron itself and transforms to finish Unicron once and for all! (With some Minicons being corrupted by the heralds to serve their side) But thats just my idea. If they do bring Unicron in War for Cybertron as the final titan for the line instead of his own trilogy id still be all for it and buy the heck out of him.
