Coming out of his recent silence with relation to additional debates, Bernie Sanders relayed through his campaign that he would in fact join Martin O'Malley and Hillary Clinton for debates. Adding caveats as Clinton had previously, Sanders asked for four DNC sanctioned debates. The debates would need to be pre-scheduled,  not on a Friday or Saturday, and could not be on holiday weekends.
Below are the announced positions for each candidate. None are what the candidate said in totality. To see what each said look at their original releases over the past few days.
From
 the beginning of this campaign Sen. Sanders has called for more 
debates. Secretary Clinton has not. Now she is asking to change the 
rules to schedule a debate next
 week that is not sanctioned by the DNC. Why is that? The answer is 
obvious. The dynamics of the race have changed and Sen. Sanders has 
significant momentum. Sen. Sanders is happy to have more debates but we 
are not going to schedule them on an ad hoc basis
 at the whim of the Clinton campaign. If Secretary Clinton wants more 
debates that’s great. We propose three additional debates. One in March,
 April and May and none on a Friday, Saturday or holiday weekend. And 
all of the three Democratic candidates must be
 invited. If the Clinton campaign will commit to this schedule, we would
 ask the DNC to arrange a debate in New Hampshire on Feb. 4.

Governor Martin O’Malley’s New Hampshire State Director Statement – January 26th
Today
 is a big victory not only for our campaign and our supporters that 
championed this effort, but it is also a victory for voters across New 
Hampshire and the United
 States.  We look forward to participating.
Secretary Hillary Clinton Remarks on MSNBC’s Hardball – January 27th 
Look,
 I’m ready for the debate and I hope Senator Sanders will change his 
mind and join us. I think the DNC and the campaigns should be able to 
work this out. I've been
 for, you know, for a long time, that I'd be happy to have more debates 
and I hope we can get this done.
I would like the chairman of the party and the campaigns to agree we can debate in New Hampshire next week.
