JoBlo.com is reporting their sources have revealed some of the potential Transformers characters and brief story points that might be in Transformers 4. JoBlo's track record is iffy at best but that doesn't mean this isn't one of the times they get it right so spoiler warning. None of this is remotely confirmed so take it with a grain of salt. If the previous movies are any indication, it will be a while before we have any real information on what TF characters will be in the movie. Thanks to Wynton R. for the heads-up.

Rumored TF Characters:
• Optimus Prime - rides Grimlock into battle in Hong Kong
• Bumblebee - rides Swoop into battle in Hong Kong
• Grimlock and the Dinobots - as Autobots somehow "brought back to life by a captured Optimus Prime"
• Lockdown - as Decepticon
• Hound - as Autobot
• Drift - as former Decepticon, now Autobot trying to regain his honor (yep the IDW comic character)
• Galvatron - "basically Megatron reborn"; unclear if summarizing the character as potentially used in the movie or his Transformers: The Movie (1986) origin
