i definitley think there is a HUGE chance that A Thousand Suns could be the album title.
why?
because just like with minutes to midnight, the title had a whole pilosophical background.
and the philosophy of it all, they felt, encompassed the theme / mood of the album greatly.
so i think with something this drawn out and detailed, it probably is the name of the album, reinforcing the new sort of theme to set forth the new album.
if it is the name of the new single, that would be great too, but that's alot of philosophy to go behind one song! (;
