well, this is pretty spiffy.
on the organe website they list displacement as one point of their wishlist for the improved render engine.
the image on the website you mentioned already looks pretty great.
in case tey will be able to include some better displacement those stuff will look even more amazing.
while i have no clue how good they could push the engine in blender cause i never saw realy good true displacements without a reyes renderer with similar memory and render speed specs.
