Despite the lack of a legal or moral imperative to do so, I think you'll see Leica address this issue as a matter of self-preservation. People like wide-angle lenses (as is evidenced by the explosion of wide-angle lenses on the market), and not everyone is going to shell out $13K for an M9 and a WATE. So should Leica forego all of the money as people start bailing for, say, the Nikon D3xs and the 17-35 Nikkor? My suspicion is that Leica will find a way to make every last Super-Angulon, Biogon, Heliar, etc., work so that it can keep its M9 volumes up. Kodak addressed radial shifts on the SLR/x series by having users shoot test exposures at a couple of apertures - and the camera itself did the computations on a one-time basis and created profiles (like Cornerfix but without involving a computer). Since this technology (and programming) has been out there for something like 6 years, it's surprising that it didn't make it into the M8 and M9. And the cat has long been out of the bag - bending the laws of physics using signal processing was already done in the M8 and is already done to a high degree in the M9.
