There you go, guys. Hope this info is interesting for you. (Also, it should be noted: there will not be any refreshed chipsets for LGA2011. Meaning, we'll still be on X79 until we get to X99. So motherboards may not necessarily be refreshed that much, similar to what happened with 990FX chipset when Piledriver came out.)
Also, the number of cores won't increase in Ivy Bridge-E CPUs for mainstream users. We'll still only have 4-6 cores. Only in Haswell-E will we see 6-8 cores. If you want those 12-core monsters from Intel, you'll have to get a server-class Xeon CPU.
Hope this is helpful to ya guys. Seeya.
