why i believe the seacons (and others) will appear on T2

i'm basing this on what happened on the ending of the first movie but i may be proven wrong.
the movie shows clips of megatron and the others being dumped to the ocean where the authorities hope no one can mount a salvage operation, assuming that they really dumped them overboard (and not stowed away at a secret lab for dissection) i believe the seacons will be appearing on the second movie.
starscream returns to the rest of the decepticon fleet and presents evidence of megatron's demise, some will believe him and others won't and assuming the megatron loyalists go to earth and do their own investigation they'll probably need the seacons to do a salvage operation on megs (assuming they really did dump him overboard). other than finback, the seacons are the only marine cons that can do the job (trypticon can travel underwater too but i doubt he can do a better salvage operation).
as for the dinobots and predacons they'll most probably be suited to appear on a third movie because i believe that
transformers 1 = fellowship of the ring (introductory movie, let's us get a feel and get used to the visuals)
transformers 2 = the two towers (once we're comfortable with the visuals and designs, Bay sics massive carnage ala siege of helm's deep)
transformers 3(?) = return of the king (more carnage but wraps up the story in a fitting ending)
that's just my opinion
