i doubt it... at least not in the foreseeable future.
BTX is a great idea, but Intel tried to make it a major revolution. AMD CPUs do not run as hot as the Prescotts do, so the AMDs do not have to have a complete restructure of the mobo's layout to compensate.
Maybe... somewhere down the line... but not right now.
