Here is some actual information...
1) Socket 2011 is intended for Sandy Bridge based Xeon processors and Sandy Bridge-E desktop processors (Top end desktop, supposedly with the X79 chipset).
2) If you know anything about Intel's roadmap, then you will know that they use a tick (die shrink) - tock (new architecture) strategy. Ivy Bridge is a 22nm die shrink of the Sandy Bridge core, like Westmere was for Nehalem, with some physical changes, supposedly using FinFET transistors for the cache, and GPU changes, apparently including on-die GPU DRAM. According to Intel slides, it will be on socket LGA1155 and supposedly backwards compatible with current boards, though I don't know how reliable that last part is. Expect them to be about 20% faster than SB on the CPU side due to the smaller process.
4) Ivy Bridge is scheduled for the beginning of next year, about the same time as Sandy Bridge hit this year, though there are rumours that they might turn up at the end of this year, to compete against AMD's Zambezi chips (Bulldozer).
3) Next new 'generation' (architecture) is Haswell in a couple of years.
