On the one hand...NOOOOOOOO! It's been the best TF series I've seen to date - well-planned action scenes, killer voice acting (especially Tom Kenny as Starscream), good writing, great characterisation, an intelligent and ongoing plot, and the toy design is just amazing. I've bought quite a few and still can't believe their articulation and all-round general awesomeness.

On the other hand, it'd be so sad to see it go on too long and get stale, or have a lame wrap-it-up ending a la the G1 Rebirth trilogy. It's been a fun ride no matter how long it goes for.
