In reply to Todd Brannon.

Most of the PC vendors have already released Haswell variations of their lineups for sometime now. Not sure about the Server side. Sounds odd when a UCS refresh with a older gen chip is being released in lieu of a newer gen version being out already.

Take a look at the high-end E5 family (Q3), I'm guessing the v2 are Haswell based.

The mid-powered E3 family Haswell versions have been available from Q2.
