It could be that 2011 Is desktop + server and 1356 could be server only then? Who knows lol, still damn early to tell exactly what's going on. 2011 desktop would be lovely jubbly, quad channel mmmmm, though would mean i have to find a single stick extra *waves angry fist*.
There's quite a few of these threads about over the past few months

Also found the MSI LGA2011 board pictures here -- http://www.tcmagazine.com/tcm/news/...1-x68-motherboard-pictured-pretty-far-release
Socket B2 is still alive and well and due for release about the same time as LGA2011
