No one on this board knows what kinds of skeletons are hiding in Dimon/JPM's closet.
IMO, if the R.2004 motion is granted and the skeletons come out, it could result in much more than a mere tarnished reputation for JPM - it could result in further litigation and criminal action. I think Dimon and JPM might give a little more than "2 $hits" to ensure that such information stays behind closed doors. From an economic perspective, it might be more cost effective for them to settle than to risk the filing of additional claims, more liability and potential criminal action.
Again, we don't know what kinds of skeletons they're hiding, but based on the circumstantial evidence available to us now I'm sure they're not pretty.
P.S. I'm looking forward to collecting that dollar in a few weeks. ;-)
