Well, I think that lens-resolution is pretty much at an end - development-wise. You know, that is not digital and it's not electronics so you cannot expect lenses to double in performance every 3 years.
Most design-benefits from new calculation programms have already been incorporated int the actual lens designs!
So don't hold your breath waiting for a jump in resolution
