Over all there are not really any surprises since most of them leaked early like Ultimate Optimus Prime, Shockwave, and Megatron. A few did grab my attention such as a first look at leader class Ironhide, a look at the Space Station mode of The Ark, the San Diego Comic-Con exclusive, and Skyhammer is the voyager class helicopter. As for prices, it is in the expected range - Leader ($39.99), Voyager ($19.99), Deluxe ($11.99), and Ultimate ($79.99).
With the release of Hasbro's official images for the Mech Tech line we might just have the official names of a few Transformers, at least judging by the posted files names. Assuming the names are accurate then green Wrecker is Roadbuster, blue Wrecker is Top Spin, and Crankcase is name of the SUV (not Dread). So far no info on the third Wrecker.
There is also a new Transformers line called KRE-O. This seems another attempt to make a Lego-like line for Transformers. The price ranges will vary going from $7.99 to $59.99. So far Hasbro has released images of Optimus Prime, Bumblebee, and Starscream. Additional KRE-O figures will be Mirage, Prowl, Ratchet, Sideswipe, Red Alert, Megatron, Sentinel Prime, Bluestreak, and Skywarp. The details and gallery is here.
