It wouldn't make any sense for Intel to release LGA2011 for consumers and put LGA1356 only for servers.
Socket 2011 Futures: A Difficult Road to Perfection
Reported by Nebojsa Novakovic on Saturday, July 30 2011 11:31 pm
Socket 2011 will be Intel's new solution for high-end desktop, workstation and server processors. While the full potential of this platform will be unleashed only with next year's 22nm Ivy Bridge-E processors, Sandy Bridge-E is still likely to dominate the top-end desktop market till then.

LGA2011: The Biggest Socket Ever
When news of Socket 2011 first appeared over a year ago, many were quite excited. This was hardly surprising since Socket 2011 will be the new solution for high-end desktop, workstation and server processors. This behemoth of a socket is so huge it requires two retention levers, one on each side, for the very first time. Despite this, Socket 2011 will retain compatibility with LGA1366 cooling solutions. The competition didn't - and still doesn't - have anything comparable, save trying to put multiple dies onto a single chip in the G34 socket.
Why such a huge socket? Sandy Bridge-E is a huge chip: the full-flavour edition will have eight cores with 20 MB of shared L3 cache on a ring bus, a quad-channel DDR3 memory controller and two QPI links. Socket 2011 also has to ensure platform scalability beyond eight cores and 20 MB of cache. Even on the 32 nm process, all this needs lots of space, not to mention power.
The new CPUs, which had originally been expected to arrive around now (Q3 2011) have supposedly been pushed back to end 2011, with some sources even estimating early 2012. It seems unlikely that Intel would further delay Sandy Bridge-E since AMD (after all those delays) is expected to launch Bulldozer no more than seven weeks hence.

There is also initial support for Intel Ivy Bridge within Mesa 7.11. Ivy Bridge is the Sandy Bridge successor that's expected to be released by the end of the calendar year, but initial support for IVB graphics are already in place within Mesa, the xf86-video-intel DDX, and the Linux kernel to ensure a better "out of the box" experience this time around.

Although not yet seen any public road map, but Sandy Bridge-E should be the next generation after 22nm Ivy Bridge-E, is expected to bring more of the core, optimized caching, richer features, the interface will continue to use the LGA2011 interface, while the release time at least until the end of 2012 or even 2013.
