Was good to see Mickyys post another thread -

"The PD-M540's use the same bearings and are sealed too.Plus they weigh the same as the PD-M770's,but are cheaper.Youre paying extra for the XT printed on the end of the pedal!"

Who would be surprised that those feckers in shimano are trying to trick us into spending more money! I just wondered how many other components or wheels or whatever are just the same with a different paint job etc.
