Should we see them in the TV show of the next series or not? Mainly to give the repainted toys a purpose for existing, also because change happens - just think at how many characters in Beast Wars got new looks because there were new toys out (okay, Rhinox and Waspinator didn't get their Transmetal forms but I would have preferred it if they did - probably didn't happen because Mainframe couldn't afford to). Would anyone really have a problem if Lugnutz started sporting his Atomic colors until the end of the TV series or until he gets a new toy or repaint? Obviously some characters are iconic - Optimus Prime, Bumblebee so maybe their new colors could be the focus of a single episode and return to their original colors by the end. Or should there be no change at all to how the characters look like? Maybe you don't care for the new color schemes or think that changing colors in the TV show just to match their new toys is pointless. Are new looks important really? Even if its just to give the viewer something new to look at while still using an old character. Its happened in almost all Transformers TV series I believe.
