I like Meyers a fair amount, but I'm still not convinced he has anything interesting or new to add to the Late Night sphere--aside from "less music" (he's said he may not even have a band or DJ), is his voice really different enough from Fallon?
How about something like what Craig Ferguson apparently does (note: I've never watched) on CBS? Something Tom Snydery?
Ferguson and Snyder are both vehicles for their hosts' own idiosyncratic voices. Meyers (at least thus far) doesn't have that kind of a distinctive voice.
