200x Sorceress, 200x Adam, and especially 200x Evil-Lyn are all overdue. Personally I'd love them to redo Faceless One, Frosta, and She-Ra (whose face we know didn't turn out right either) if they ever get to where redoing figures (or just heads) is a good idea.
The trouble is, Mattel didn't set out to make those mistakes, so it's no guarantee that Super7 won't run into similar problems as what befell PD Teela. I hope they are able to overcome them since she was a very disappointing figure in the line from Mattel. And I hope that Teela is in the next year of Club Grayskull like you do, but more than anything I hope she's a good figure. If that takes an extra year, I'd prefer that to rushing her out with melted nose or something.
