I hope they are able to work everything out. It's really a huge shocker on one hand, but yet in the other you're kind of surprised after all that touring for so long it hadn't happened sooner.
I think they'll still do something. Mac and Laura broke up in Superchunk in 1993 and the band is still together today, touring and releasing new music. It's sporadic, yes, but I'd rather see minimal SY activity as opposed to none at all.
