What I'd like to see is a completely new watch - a different case from the two they've been aggressively reusing. If they reuse this case anymore, I think they risk destroying any value they've created with their designs, similar to what Seiko does with any of their popular watches.
If it is a three hander, I'd like to see a different movement. Miyota has upgraded their 8 and 9 series movements earlier this year, so I hope they get with the program and move to the new movements. They appear to be better across the board.
A manual wind movement would work perfectly with their aesthetic and I would love to see that, but I'm not sure if the rest of the customer base thinks the same.
So I agree with @conrad227
and a larger case would be a smart move too.
