Does P67 fully sopport to Ivy Bride & PCI-E 3.0

Yes z68, p67, h67, and h61 will all support it. All you need to do is a simple bios flash.

Intel is claiming that Ivy Bridge will support those chipsets but they are also going to be releasing a new chipset with the release of Ivy Bridge and it's going to be up to the motherboard manufacturers to follow through with thier support of those chipsets or they may just concentrate on the new chipset. We can speculate all we want but we will just have to wait and see what happens.

i think motherboard manufactures has followed through wiht their support of those support, it can be seen when P67 has come with his PCIe 3.0.
but its good advice "We can speculate all we want but we will just have to wait and see what happens. "  

thats mean nice news bro  
but there is not manufatures that produce motherboard with PCIe 3 on p67s young brother.
