James, I think it's a bit of a stretch to suggest Google will hit exact match or keyword domains hard.
If the content farmer update was anything to go by, I doubt it will impact anyone who builds quality sites for the long term. Parked EMD won't be affected as they don't rank in the first place, so who exactly will this change impact in a significant way?
Sure, Google might tone it down a little but what else are you going to do? Purchase a non-keyword domain name? I doubt it. In most cases people will still opt for keyword based domain names and it's the correct move regardless of what Google does.
