I do not have the Panny 20mm so the new 17mm looks very compelling.

Frankly, I think it is a great lens compared to the competition. I'm looking at the Lenstip resolution charts for the old Olympus 17mm 2.8, and that old boy beats the following lenses, hands down:

Pentax smc DA 35 mm f/2.4 AL

Canon EF 35 mm f/2.0

Samyang 35 mm f/1.4 AS UMC

Carl Zeiss Distagon T* 35 mm f/2 ZF/ZK/ZS/ZE

and probably others.

Obviously there are other factors to consider than just the MTF chart, but both the old and new Olympus 17mm lenses appear to be "world class" lenses from a resolution point of view.

Any big flaws in my analysis?

Beware, because some reviewers aren't offering really comparable results when you change format. I don't remember what Lenstip does, but you should read about their method before drawing any conclusion directly from their numbers.

Exactly, if you have test results on cameras with the same MP count and you then integrate the LP/mm to LP/PH (picture height), you start to get somewhat comparable results (but you still have different AA filters to contend with).
