Leno is probably ready to retire from the daily drudgery of doing a daily show for 9 months+ a year. After this many years it has to be a drag ... and he does NOT need the money!! (per the reports he has lived WAY below his income for many years - OH ... and most importantly on his personal financial front ... NO DIVORCE PAYMENTS to an "Arm Ornament" GOLD DIGGER!!)

Fallon is a LOT funnier than Conan ever was, so I think this transition will happen and be good for everybody (Leno, Fallon AND NBC)
