'Jon & Kate' and their 'big announcement': Your guess?

Apparently there will be a "big announcement" on "Jon & Kate Plus 8" on Monday's edition of the TLC show. Will they throw in the towel on the reality show and focus on fixing their very public marital troubles? Will they tell the world they're divorcing? Will Kate's haircut announce that it's getting its own Lifetime spinoff?

Whatever it is, as James Poniewozik points out, the couple is, as usual, milking every possible drop of publicity out of the announcement. As he writes, "It's hard to feel badly for a couple suffering in public when they're working so hard to get the largest possible audience for their suffering in public." Pretty much. Though as I said here, it's hard not to feel sorry for the kids caught in the middle of all this.

There's of course a promotional video for Monday's brouhaha:

And on Twitter today, there was a lot of tongue-in-cheek speculation about what the big revelation could be:

• From @justinfinnegan: "Kids are getting too old, bringing on a younger obnoxious cousin. Also adding an animated sidekick only Jon can see."
• @2zen2: "Kate's really a man, Jon's running off with Cirque du Soleil & the kids get a normal life.''
• @elgray: "Another J&K possibility: Jon leaving Kate for Octomom, better working conditions."
• @amytvgal: "Survey says they'll be on the 'Family Feud' playing against the cast of 'Raising Sextuplets.'"
• @hitfixdaniel: "I'm hoping Jon & Kate are going to space!"
• @bjwaggoner: "Jon & Kate Monday announcement is: Kids emancipating selves."
• @TNRLM: "Jon & Kate selling kids to Angelina & Madonna."
• @franklinavenue: "Two new shows coming to TLC: 'Kate Plus 8' and 'Jon.'"
• What's your guess?
