This is merely an observation and just an opinion.
Due to the recent information about Transformers 4 containing Dinobots, the general feeling is that this film may be the live action remake of 1986's The Transformers: The Movie.
Not only will TF4 contain The Dinobots, but it will also contain Galvatron- who is the reincarnation of Megatron himself. And how was Galvatron created? By Unicron of course.
That being said, be expected to see a different version of Unicron or at least not many scenes containing him; due to the budget of the effects. But, with Kelsey Grammar keyed to play an "ancient evil", my thoughts go directly to Unicron.
So do you think my judgement is correct? Do you think Unicron will be in Transformers 4? Do you think it will be a live action remake of the 1986 hit with the death of Optimus Prime and the rise of Hot Rod? Well we will see when filming begins soon.
