They look too G1, and not in a good way, they don't seem to add much more than a few extra joints.

Nightfang might be ok, but I by far prefer TakToms Rumble and Frenz, while cassettes were cool in the 80's it's all kinda a bit retro now, like in that Robot Chicken skit. I have no problem when Soundwave and the cassettes update their alt modes to something more relevant.
