Isnt the finale going to be like a two parter movie? mebbe we'll see the other beasts there... if so that's kinda really short exposure there with no real character development at all a sit would be the first and last time they appear.

Unless they're ending TF Prime and picking up from there for another new show - kinda like Beast wars to Beast Machines - though hopefully not as bad a transition. Im guessing the budget for CGI just couldn't be stretched for all the other beasties ...shame
