Why It'd Be Awesome: The logic here is that while each of these cinematic properties on their own ranges from tolerable to terrible, they all might benefit from a little extra interaction, especially if it meant that The Rock could appear in a Transformers movie as Roadblock. Plus, considering that neither G.I. Joe nor Battleship have exactly shown themselves to be box office dynamite, the prospect of Optimus Prime having a cameo in a potential sequel would give each film a substantial boost. But yes, mainly it's because who wouldn't want to see Dwayne Johnson smacking around robots? How Likely Is It?: 5/10. Granted, the Transformers guys are already pretty busy putting together their own "Transformers Cinematic Universe", but given its self-contained nature, there's no reason why this couldn't tie into the bigger Hasbro picture at some point. It can absolutely happen, it just depends on timing and a bunch of other boring factors.
