For the 5,863,284th time: there is no telling if the P4EE's power and cooling requirements will be compatible with what today's laptops are able to provide. So even when the chips do finally come out - which is in the future, not today - there is no guarantee it will be physically possible to run them in Sager laptops. Yes, they'll probably work, but no one can make any promises right now.
To get the P4EE into Sagers, first Intel has to release those testing units to manufacturers, including Clevo. Then Clevo has to perform exhaustive tests of the chips in the laptops to ensure the P4EE is compatible with the power and cooling systems in those laptops - and possibly make necessary modifications to those systems. Or even decide the necessary modifications would be too extensive and declare the P4EE incomaptible, although that possibility seems remote.
Anyways, the process could take a while, so don't hold your breath.
