I think it's more that the "mainstream" computing has moved on from desktops to laptops.

Instead of targeting the latest and greatest design at 130W/90W TDP desktop parts and downsizing it to a laptop, they've turned it around and is starting to target 35W TDP as their main platform, then upping the power to turn it into a desktop part.

Since power consumption and heat dissipation is becoming an issue also at their top-of-the-line server market, it probably makes much more sense to design things that way. My guess is that high density server design at this point has more in common with laptop-esque power and heat constraints than those of, say, high-end workstations.
