Are the fallen Megatron and the boys who were dropped into the ocean?
This is what I found on the Wiki about Fallen. Is this accurate?
Although the Fallen's origins are only suggested in his comic book appearance, they would be fully explained in Dorling Kindersley's Transformers: The Ultimate Guide. One of the original thirteen Transformers created by Primus, the robot who would become the Fallen betrayed his creator by siding with Primus's dark twin, the malevolent planet-eater, Unicron. In the final battle between Primus and Unicron, the Fallen fell victim to the same fate as his master, sucked through a black hole into another dimension. However, while Unicron emerged into another universe, the Fallen was not so fortunate, finding himself trapped in the "underspace" between dimensions.
 Dreamwave Productions The Fallen made his only appearance in the second volume of Transformers: The War Within - the Dark Ages. Around 6.5 million years ago, a test of the experimental "space bridge" matter-transport system on Cybertron liberated the Fallen from his prison, and he materialized on Cybertron, where he quickly recruited the Chaos Trinity, three mystically-inclined Decepticons - Bludgeon, Mindwipe and Bugly - into his employ. Abducting Transformers that he identified as possessing "genetic potential" within their sparks - Grimlock, Blitzwing, Jetfire and Hot Spot - the Fallen planned to use their energies to awaken Primus from his self-imposed slumber, thereby alerting Unicron to his location, allowing the world-eater to renew hostilities with his old enemy. An attack from combined Autobot and Decepticon forces led by Shockwave and Prowl disrupted his plans, and Primus himself reached out and promptly destroyed the Fallen.
Even though nothing seems to be certain about the new movie, I think it's safe to say that "Revenge of the Fallen" isn't referring to THE "Fallen". That story/character is isolated in the comic universe, unless I somehow missed an appearance elsewhere. So, keeping in mind that nothing has been 100% confirmed or denied, I think they're talking about the dead bots.
That said, if anyone finds and wants to post any spoiler-ish info about the film and it's characters, feel free, but please mark it as such. I, for one, would like to still be a little surprised on opening day.
********a subtle Spoiler follows so here is a warning*****
From the Wikipedia entry on the movie, comments on the Superbowl trailer, and apparently some stuff from Bay ( Nick de Semelyn (February 2009). "20 to watch in 2009". Empire: pp. 67-69. ) it appears that the movie and some associated poster images:
are indeed the character the Fallen.
Apparently he is the big guy in the giant wheel toward the end of the teaser.
It occurs to me that Ravage can't possibly have an alt mode that is anywhere near as cool or as effective as his robot mode...unless he does gestalt somehow with Soundwave, which would be awesome.
One idea going around is that the missiles raining down on the ships at the begining of the trailer are Ravage (and others?) being "shot" by Soundwave from orbit. That's why Ravage is coming out of the ocean on to the beach in the trailer. Talk is that Ravage has an alt. mode very similar to Frenzy from TF1 but with some metal "dreads" (a puppet looking like this was seen on set)
That is just one part of Devastator. If the rumors about the toys are to be believed, the Constructicons will all be of the Voyager-class size, combining to make a robot roughly 2 feet tall. Which means he may turn out to be even taller than G1's Fortress Maximus. Quite a feat.
