I just saw the news of the King Grimlock release and saw someone complaining about the size issue once again, so it got me thinking. I don't know if it was intentional or not, but Grimlock in T. Rex mode is in scale perfectly to MP Prime in truck mode. If you look up a size comparison chart for a T. Rex and a human and then then compare the size of the human to a Semi cab they are almost perfectly in scale. Granted I know in the cartoon Grimlock was HUGE but I'm just throwing it out there as a possible reason why he was designed "too small". Unfortunately it doesn't explain the MP seeker mold size as he should be much bigger to be in scale with Prime. I've never heard anyone complain about Starscream being small though.
