Looks like there's going to be a short epilogue showing Hurley in his role as the new "Jacob" included with the Complete Series DVD set.
Also, ABC elaborated on the final shots of the plane wreckage on the beach, saying:
"the images shown during the end credits of the Lost finale, which included shots of Oceanic 815 on a deserted beach, were not part of the final story but were a visual aid to allow the viewer to decompress before heading into the news.”
