yeah but the Targetmaster Hot Rod toy would have probably already been planned by time Season 3 was ending - remember it takes about a year to design a Transformer, and while TM Hot Rod was a retool, they may have already decided to retool Hot Rod, Blurr, Kup, Cyclonus and Scourge early enough that they directed writers to make Rodimus Prime revert back to Hot Rod by season's end.
