I don't have numbers any more than you have numbers indicating that WotC and Paizo aren't competing, so let's just drop that line of thinking, OK?
But maybe you aren't getting out on the message boards enough. Even here I'm seeing people discussing how much better Paizo adventures are than WotC adventures. If you think that's not resulting in some people choosing to buy the Paizo adventures over the WotC ones with their gaming budget, then I don't think we have views of the gaming world even remotely compatible.
I am one of those who thinks the PF Ap's are vastly superior than WotC's. However, the point of modules, for me and many others, is that we don't have the time or inclination to create our own. So your assertion (if I am reading it correctly) that there is a large segment of 4e players that buy PF AP's to CONVERT to 4e, seems counter intuitive to me.
