Intel definitely wants to roll out a new chipset after the Sandy Bridge P67 and H67 debacle but it will take them until end of the year before it happens.
Codename for Ivy Bridge 22nm CPU chipset is Panther Point. The new chipset is going to end up with Intel 7 series brand, most likely P77 and G77, but it is too early to tell. It has 1Gb LAN support, PCIe 2nd generation support as well as SATA 3.0. Furthermore, it supports USB 3.0 and 2.0, which is the first time ever for an Intel chipset.
The surprising thing is HDMI 1.4 as well as DisplayPort 1.1. Ivy Bridge will be the third generation of Intel's CPU that features graphics support, and therefore Panther Point's DisplayPort and HDMI support will be put to good use.
The official launch date is currently scheduled for 1H 2012.
