VR Zone received some details about Intel's LGA2011 plans, you can check it out on their website. This is the platform that will replace LGA1366.
What we do know is that the new boards will use quad channel memory and we're expecting one DIMM per channel on most if not all consumer motherboards. The CPUs for the LGA 2011 platform that targets consumers are currently known as Sandy Bridge-E, a CPU which will also appear as high-end Xeon processors. This will be Intel's first PCI Express 3.0 platform as well, but don't expect to see boards with more than two full x16 PCI Express slots, just like the current LGA 1366 boards, although it would be possible to do boards with up to five slots with eight lanes worth of PCI Express 3.0 bandwidth per slot.
We'd expect to see the first boards from Intel's partners on display at Computex 2011 which starts on the 31st of May this year. However, the platform isn't really expected to launch until a few months later, maybe during IDF San Francisco in September.
