Fall TV Predictions: Glee Bust-Ups, Blair's Fate, An Engagement, The First Cancellation And More

Before signing off for good, The Office will reveal either Toby or Will Ferrell's DeAngelo Vickers as the Scranton Strangler.

Either Peter, Olivia or Walter will truly and sincerely die in the Fringe series finale.

CBS STACKS THE TUESDAY DECK |

Since Golden Boy failed to shine — and with CBS needing to move one Thursday drama to make room for a second comedy block — TV's third-most watched drama landed in the Tuesdays-at-10 spot, right behind No. 1 and No. 2. POI fans seem to be thrilled (which on the Internet means "not furious") with the move, while NBC's Chicago Fire, even after moving, again finds it facing off with a venerable CBS procedural.

On any ... given day, TMZ will report ... that Britney and Demi and/or ... Nicki Minaj and Mariah are feuding back ... stage.

Dexter Season 7 will be so compelling, we'll forget all about — and yes, maybe even forgive — Season 6.

Glee's "Break-Up" episode (airing Oct. 4) will mark the end of "Klaine" and "Brittana." Also, Elton John will be unmasked as Sue's baby daddy during November sweeps.

A Once Upon a Time character that we now consider a "friendly" will change allegiances — voluntarily or not so much — and ally with the Evil Queen.

Bones' Booth and Brennan will be engaged by the end of the season.

A five-member boy band — just like One Direction — will prevail on the "shocking" Season 2 finale of The X Factor.

Nikita's ratings will not take a major hit, despite the fact that it now has the worst/most incongruous lead-in ever in America's Next Top Model.

Proving that love always comes when you least expect it, Bachelor Pad's Blakeley will marry single dad Tony before The Bachelorette's Emily ties the knot with Jef.

Nudged and shoved by the NFL overrun and now going up against ABC's juicy Revenge, the acclaimed The Good Wife will, sadly, see less-good ratings, prompting talk of a move back to Tuesdays.

A total of zero Smallville series regulars will guest-star on The CW's Arrow during Season 1.

Despite its best efforts, Private Practice will wrap its run when Kate Walsh exits after 13 episodes. As many as two of its cast members will then be "transplanted" to Grey's Anatomy, while a third will land on Scandal.

So You Think You Can Dance's Witney will wind up as a Dancing With the Stars pro.

CBS' Elementary will be the first new series to earn a full-season pick-up.

The Vampire Diaries' Elena and her pals will be held back when Mystic Falls High realizes the kids never go to school. Thus, the show's graduation problem is solved! Also: Secret Circle alum Phoebe Tonkin will be made a series regular shortly after making her guest-star debut.

Mindy Kaling won't just see The Mindy Project land Fox's first full-season pickup among its new shows, she'll also emerge as an Emmy nominee next July.

Hawaii Five-0's next "Lost reunion" will involve Evangeline Lilly.

Christina Aguilera will have a "wardrobe malfunction" during a live performance episode of The Voice (as will Gilles Marini during a live installment of Dancing With the Stars). Also: The winner of Season 3 of The Voice will be a contestant who's cut during the Battle Rounds and then snatched up by a competing judge.

NBC's Guys With Kids will be the first new show pulled from its network's schedule; Community will grab its spot, dodging a grim Friday fate.

Revenge's Ashley will turn out to be pulling strings we never thought her possible of holding. Also: Season 2 will end with Emily triumphant. In turn, the disgraced Grayson clan will be the ones entering Season 3 seeking – all together now – revennnnnnnge!

Don't Trust the B—- in Apartment 23 won't (just yet) nab Katie Holmes for a Dawson's Creek reunion. But after Busy Phillips' previously announced drop-by, the ABC comedy will also feature at least a good-natured cameo from Joshua Jackson.

Clay won't live to see the end of Sons of Anarchy's fifth season.

In its Wednesday, après-Arrow time slot, Supernatural will improve its numbers, making it the new Smallville. #10seasonsandamovie!

Mark Pellegrino will continue his genre-TV guest-star streak with stints on NBC's Revolution, ABC's 666 Park Avenue and The CW's Arrow.

Tony nominee/Grammy winner Andrew Rannells will sing during a musical number/episode on NBC's The New Normal. Also: By November, NBC will move The New Normal in front of Go On on Tuesdays.

Chuck and Blair will reunite in the Gossip Girl series finale, but a flash-forward in the final minutes will reveal that she ultimately settled down and had children with... Dan!

In a separate but possibly related prediction: No one will be satisfied with the Gossip Girl series finale. No. One.
