I think the requirement is for the motherboard to have UEFI. So for instance my Gigabyte P67 UD4 is not likely to support them but all my Asus are supported. So it's still best to check each manufacturer to be sure.
But yes, for people who already own 1155 boards, not much to gain from that upgrade.
