Random thought: Let's consider this as if it were verifiable information for a minute, and assume that Intel doesn't care about the tiny percentage of people who overclock (and spend loads of money on CPUs anyway.) Maybe there's a reason for them to restrict it? For example, what if they are looking at 22nm (or whatever the next shrink is) samples and figuring out that the silicon can't handle any more voltage than they are planning to put through it at stock speeds? In that case it would make sense to start weening us off in advance to lessen the shock later. There would be no market risk (AMD) because they are subject to the same physical limitations as long as they don't have some ridiculously advanced technology.
Probably a nutty thought, but mostly logical.
