Thats true, in the more recent comics Galvatron and Megatron existed as seperate entities when Galvatron was following Nemesis Prime, they could easily follow this route in the movie and have it build up to Unicron.

Shockwave heads to Earth after losing contact with Megatron, and is the villain for 1 movie.
I wonder if they do end up bringing in Galvatron, if they'll give him Cyclonus, and Scourge as minions. Given that all of Megatron's top soldiers died, they need to fill some empty spaces, not just Megatron's.
Shockwave should never have been killed off, what a waste of an awesome character and potentially superb villain. They should have just used another character in his place as Shockwave, one of the best villains in TF lore, was just simply wasted.
Although there are still other villains they can use, Thunderwing and Sixshot come to mind.
