GRD lens evolution

While looking at the lens of the GRD3 I realised, that there is even enough "room" for a f/1. Provided the sensor size doesnt change, of course.

What do you think, will we see a 28/1 GRD in a couple of product cycles?

On my part: I sure hope so.

Edit: And the DOF would be like 28mm/4 on a 35mm camera. I really like how that sounds.
