Maybe tomorrow (piano ver.)

 is a track in Xenosaga Episode III. It has not been released on any soundtrack or sound selection and not much is known about this track. It is a piano version of title screen, and by extension, of maybe tomorrow~ending medley (it is distinct from title screen (piano ver.), being somewhat faster).

It does not play in Xenosaga Episode III - it was stored within the game's files but went unused.
