That's a rather popular opinion, though, isn't it? Lots of people aren't too keen on the newer designs and that's alright because we're all allowed to like and dislike what we want.
However, it's definitely not worth worrying over the unknown. I have faith in GF and I believe that they will present us with a good, solid list of new Pokemon. For every Heatmor, there is always a Lilligant.
