Ivy Bridge-EP Xeon E5 Question

I am looking to get back into video editing and encoding in the near future and while the current systems that I built several years ago have served me well, they will just not cut it for FULLHD work. Thus, I am really considering a dual socket Xeon E5 build when these processors are released in few weeks/months as I do not think I could wait for Haswell-EP) in late 2014 or early 2015.

Based on the leaked information, my choices are two of either the below chips listed here:

Model: Xeon E5-2643 v2
Cores/Threads: 10 / 20
Frequency: 3.5 GHz
Cache: 25 MB
TDP: 130 Watt

Model: Xeon E5-2687W v2
Cores/Threads: 10 / 20
Frequency: 3.4 GHz
Cache: 25 MB
TDP: 150 Watt

However, I find the specifications somewhat odd... Why would the lower TDP chip have a higher Frequency and the Higher TDP have a lower Frequency? Could an overall higher Tubro speed accompany the higher TDP? The "W" stands for workstation, correct?

Current Xeon CPU are strap locked are they not? So unless Intel changed their policy with the new Xeons, overclocking should not factor in here. But based on the higher TDP and the Sandy Bridge Xeon E5-2687W, I have a feeling the Xeon E5-2687W v2 will have a higher base/turbo clock when they finally release.
