Looks like the December 27th debate is just Gingrich and Santorum now:

Michele Bachmann, who has met with Donald Trump four times, is also a no-show for the debate he's moderating, per David Brody.

Are they going to go through with this debate? Gingrich has already very loudly thrown in his lot with Trump, Santorum desperately needs attention, and Trump's ego won't allow him to back down. What do you think?
