one the G1 thing, I dont blame Bay. His movies were not about G1 line. the only G1 movie was the 1986 Transformers the Movie.

the problem with his movies are :-
1. weak plot
2. plot holes
3. too much US 'supremacy'
4. too much human elements
5. Shia screams like a girl
6. too many toilet and hillibilly kinda jokes
7. megatron FINALLY got an earthmode in TF3
8. too much focus on Prime
9. too generic kinda decepticons. one template fits all
10.the alternate mode vehicles choice. too many american cars, supercars. which defeats the word 'blend in'

I got it less than RM500. It is a masterpiece. I have MP-10, MP-22, FT Scoria, MP-12 and Hexatron quality top them all. Feel solid. Then again, there is a 3rd party making KO of Hexatron with diecast part...

Speaking of G1 combiners, i searched my old stash and found these   


Anyone remembers them? 
Bot Mod

Combined Mode

  I m sure there are No Reissues for these guys unlike MP Series. Even KO(s) don't come close. 

Maybe not. Headmaster variant came from TF japan franchise, most likely it'll come from takara. Hope they'll come up with masterpiece variant headmaster optimus where he's actually human wearing gold bangles.
