The SERPs with regional domains are fine, I can see why that might be the case, however, when a .com has all the baclinks, even from the region, yet it is nowhere to be seen. That is the problem.
IP-based delivery is a different issue, if that's what you mean. Most of the time, the IP-base delivery that i've seen is inaccurate.
Bing regional giving prominence to regional domain over .com is a weird accessment. It just means that we have to retain regional domains for Bing.
