From TFW:

Rattrap is as you can see in the image based on his season 1 beast mode. The image in the magazine shows Rattrap comes with two guns, most likely they combine to make the larger gun shown on the cover. His beast mode is an organic rat, nicely detailed but it seems to lack some poseability.

Tankor is likely to be the star of this assortment, for those wanting show-accurate Beast Machines toys. His robot form is nearly spot-on to how the character looked in the Beast Machines series, with the tank mode sporting the semi-exposed head which was something of a trademark for Tankor. Plus he sports a Vehicon faction symbol - making the Vehicons the sixth faction represented in the current Transformers Generations series.

Crosscut is as some anticipated a silver redeco of Skids, with a new head. The new head seems to be based on the original alternate head design of Diaclone Skids, later used on the exclusive E-Hobby Crosscut and Generations book Screech figures.
Not surprised that Rattrap's rat mode lacks poseability.

Show accurate Tankor is really a pleasant surprise though. Hope they'll give us more BM characters. Pretty much anything they will be a huge improvement in terms of show-accuracy.
