Michael Bay returns for TF5 as director

[Bladestorm]

Filming for TF5 will begin in May, so by mid-year we will get our first looks at scenes and maybe some props of robots (like heads on sticks and their car modes).

Would that mean the voice actors are in the studio now? )or would be VERY shortly?
With the last film they had all of Optimus' preliminary dialogue recorded so the on-screen actors could emote to it.
