What is Shockwaves' objective on Earth?

Heya Folks! Just curious as to what we all feel Shockwaves' objective might be. I'll "spark" the discussion.
In accordance with G1 lines:
*Shockwave wants to penalise Megatron for abandoning the Decepticons, or else for claiming he is Decepticon leader after Shockwave got the job.
*He's simply found a nest of Autobots, and is here to exterminate.
In accordance with previous films:
*Shockwave wants to penalise everyone who permitted the fallen to die.(In a dictatorship, being present when your founding father is killed and yet surviving the event yourself is a pretty much high treason on its' own).
*Shockwave wants Cybertronian artefacts (the Matrix of leadership, the tomb of the Primes,fragments of the Allspark, the remains of the Sun Harvester) in Cybertronian possession.
In accordance with talk about this film:
*Either Shockwave,Megatron or both (remember:they might be rivals!)are assasinating particular Human leaders, with roots of their reasons manifesting in the history of the Space Race.
Further speculation:
A possible Russian (amongst other) version(s) of Sector 7 falls victim to Decepticon activity,potentially releasing even more previously 'frozen' Transformers into the fray.
Any thoughts???
