their alt modes were quite different though. MMCs Arcee had a more cybertronian hover car design vs the g1 arcee rubber wheels futuristic earth car mode.
MMCs Sphinx however looks bang on G1. Which isn't a good move considering what happened to FansToys 'Soundwave' It also means a lot of people will hold out on MP scale toys if they feel an official Takara version will ocme out soon anyway - pretty much how I feel about that mirage and sunstreaker.
At the moment, Takara seem to be focused on Autobot cars from the 1984 toy line so thats something.
