So, I'm betting these headphones will be more likely to be wood holding the drivers with metal cups. I would even go so far to bet that the metal cups are going to look like the mahogany RS1 in shape. They will probably have the nice new thicker cable as well. I guess that would actually make them look a little similar to the HP-1000, maybe they would even have it black anodized, that would be great.
I am really only hoping that there is no gold/brass involved, just silver/aluminum except for maybe the headphone plug. No buttons, just like these:
My whole line of reasoning here is based on Grado not being able to be all that creative with their original designs. This just seems like the obvious thing to do. I wonder how plastic hinges would look with that, they wouldn't be hidden like they are by the PS1000. It would be a sure hit for me if it took some fashion hints from the hp-1000 for metal hinges too.
