Is there an end game?

Digital cameras are developing fast and in two-three years those cameras will make your current models look ancient.  I have a few questions.

1.  Is there a point we say enough we don't need a better camera?

2.  What is the future camera in 10 years?  I think it's going to be a range finder style camera similar to the e-x1 or nex6 or rx1 (but interchangeable)

3.  What is the perfect camera?  Are we almost there?

Here is my criteria.  Good 3200 iso.  Full frame dof control.  Small and lightweight.  Fast focus and functionality.  EVF or optical viewfinder.  Interchangeable lens.

The RX1 almost hits these.  I don't see the perfect camera very far behind.  What do you think?
