A few weeks from now, the late-night TV landscape will look drastically different, what with current 'Late Night' host Jimmy Fallon taking over 'The Tonight Show' from Jay Leno, while 'SNL''s resident Weekend Update anchor Seth Meyers graduates to 'Late Night' in turn. The first promos for these takeovers have emerged, but will everything be ready in time for opening night?

The first of NBC's promos for 'The Tonight Show starring Jimmy Fallon' looks back at a retrospective of hosts through the years (neatly sidestepping that whole, Jay-to-Conan, and back-to-Jay matter), of course lending the focus to Fallon, and some of his more memorable 'Late Night' bits through the years. Meanwhile, the 'Late Night with Seth Meyers' first look includes 'SNL' players Cecily Strong and Kenan Thompson as the Weekend Update anchors leave their desk, before Seth's tour of the new 'Late Night' studio goes very wrong.

It all leads up to NBC's coverage of the 2014 Sochi Winter Olympics, after which 'The Tonight Show starring Jimmy Fallon' debuts on February 17, followed by 'Late Night with Seth Meyers' own premiere on February 24. Do you think either host will be up to the task?

Check out our first looks at late night history with the 'Tonight Show starring Jimmy Fallon' promo above, and stay up for the 'Late Night with Seth Meyers' promo below!
