locke has seen the ending

John locke, when descirbing how he looked into the eye of the island - ie the smoke monster, he described it to Mr Echo as 'beautiful' , since then he went on a mission, his faith etc...

when matthew fox and darlton etc were quizzed on the ending off the show they descibed it as beautiful, some would like it , some wudnt etc...

i wonder if when john locke did look into the eye of the monster he saw something that will coincide with the ending of the series...

just a thought, if anybody cares to elaborate then would be much appreciated...
