Obviously something is wrong with that report. Not to mention that there is absolutely no way Nehalem will require an insane amount of voltage to hit 4GHz, while the latest Core 2s can hit 4GHz at 1.2-1.3V no problem. The core is pretty much the same, and with an unlocked multiplier the changed infrastructure should not be a bottleneck.
1. Static logic leaks less, thus voltages don't seem that dramatic? This factor is a pretty big departure from Penryn.
2. Bloomfield like Barcelona is a big core. Big dies normally dissipate heat easier (provided distant hotspots and all) compared to Penryn/Wolfdale.
3. It's not as simple as that. Or OBR and co. would be getting 4Ghz OCs too.
