Re: Transformers 4 is going to be AWESOME.
^Ultra Magnus does seem the most likely, but it wouldnt surprise if Bay gave the Dinobots vehicle forms at some point during the movie, so if this turns out to be Grimlock I wouldnt be shocked.
I love both characters so would be happy with either, although I prefer Ultra Magnus.
