First up, from TF08.net, an image of Sideswipe in his Centennial Corvette vehicle mode to go along with the one image from last month. Sadly no robot mode pictures or packaging to verify officially that the name of the character is Sideswipe (the Hasbro Summit second hand information is not quite conclusive enough).
Next via TFW2005 is Megatron which may or may not be the Fast Action Battler tank mode. Looking at previous images, I think it’s the Deluxe class version as the legs and turret design don't look like the FAB version.
The-Arker.com brings us two new images of unknown class of Starscream, at least it doesn't look like the Voyager class to me. My best guess is it’s the Deluxe class but I really can't tell.
