I'm pretty positive that the Dodsons designed her current look based on Heinberg's script for the first issue, which gave no indication that we'd ever see animal-like Cheetah again (and, indeed, implied we wouldn't). So I put the blame for her current look squarely on Heinberg's head.
Mind you, I don't like the "new looks" that the Dodsons gave Cheetah, Psycho, or Giganta. Their old designs were perfect, the new designs, while done by skilled artists, were a step down. Ultimately the new designs were put in not because the characters needed redesigns (they didn't) but because DC wanted to beat readers over the head with how SPECIAL Heinberg's abomination of a relaunch was. It's a new chapter for Wonder Woman! A secret identity! A new boyfriend! New looks for all her foes! Everyone written completely out of character!
