Currently second on the late-night docket at CBS, Craig could be poised to time-shift from 12:30 to the 11:30 time slot. There are a few caveats to this potential move: while CBS dominates older-skewing demographics, Jimmy Fallon’s younger audience is the preferred demo for advertisers. Ferguson is funny enough, but he’s not in prime, or, no longer in his prime long enough to significantly host the Late Show.

Stewart’s contract with Comedy Central expires next year, opening him up to some potential options. He’s hosted The Daily Show for 18 years now and while his shows are still top-notch, he may be looking to take his act somewhere else. As opposed to friend, Stephen Colbert, he could easily transition his show from cable to network by toning down the snark just a little bit.

Talk about perfect timing: Handler just announced her Chelsea Lately show will end later this year when her contract with E! expires. We could see her as a good successor to Letterman, although Handler arguably doesn’t overlap with much of CBS’s strategy, this could be a time for the network to reposition itself to fit a younger audience.

We all know the sordid tale of O’ Brien’s takeover and demise of the Tonight Show a few years ago. While that’s water under the bridge now, he seems happy at TBS, we wouldn’t be too surprised if he followed Letterman’s footsteps – he is, after all, similar to Letterman in that they both were in poised to take over the Tonight Show at one point or another, but Jay Leno’s primetime show failed, bumping O’ Brien, and Letterman was passed over for the spot post-Carson for being too snarky.

Did you know the Stephen Colbert you tune into Monday-Thursday night at 11:30 p.m. is actually a character? The real Stephen Colbert is much less cartoony, more serious, and a helluva lot more dedicated to his craft. Here’s the thing about Colbert leaving his show on Comedy Central for CBS: that character would mostly likely have to go, leaving the real Colbert much more restricted with what he can do, creatively.

Whether it’s behind the desk at Weekend Update during her SNL days, or hosting award shows with America’s BFF, Amy Poehler, Tina Fey can hold her own when it comes to comedy. We think she’d do fabulously behind the desk at Late Show but we wonder how she’d feel potentially going toe-to-toe against former co-Update anchor, Jimmy Fallon.

Coming off nine full years at CBS with HIMYM, tapping NPH to fill Letterman’s shoes would not be completely surprising. He’s the right age – neither too young or too old – has mass appeal, likable and funny on his own and great during interviews. He’s currently doing a stint on Broadway in Hedwig and the Angry Inch but once that ends, who knows? However, we’re not sure if he’d want to commit to a show like Late Show so soon after finally being relinquished from his Barney suit.

Honestly, it may be time for Ryan to hang up his many hats and just settle back into the late night landscape. After all of the shows, events and programs he has hosted over the past decade or so, we wonder if he is tired of jumping around and would like to settle down at a network for the next few decades.

There is some discrepancy about whether or not Ellen could theoretically host her daytime show and move into the last night stratosphere. Her contract to Ellen doesn’t end until 2017 and her audience for daytime is huge, which makes us think she’d be unlikely to refocus her attention anywhere else for a while.
