The chipset that is going to replace the X58 on the long term is going to be X79, and a slie on it leaked yesterday. Intel's next platform for enthusiasts will get a 2011-pin LGA socket, the Sandy Bridge-E (enthusiast) processor that features a massive quad-channel DDR3 memory controller and 32+ lane PCI-Express 2.0 hub, and the X79 chipset.
Intel might actually skip the 6-series chipset family with its next high-end platform chipset as the platform is slated for Q4 2011 already, though Z68 will still be launched, but as a Premium chipset.
