What motherboards will support ivy bridge and what will be the Socket?

Ivy Bridge is LGA 1155 socket. From what we've seen, any consumer-level H67/P67/Z68 mainboard will support it with a new BIOS version. However, not all of the new features will be supported, like PCIe 3.0.

There will also be new chipsets coming out for Ivy Bridge ( _75 and _77 series) that fully support the new features.
