I'm haven't seen any info to convince me otherwise but IF WMI did indeed possess interests or a stake in MBS interests retained by it's SPE subs, we could indeed see some form of reasonable return.
The theory is relatively simple in that it is 100% confirmed that WAMU retained interests in it's securitizations, but, what is still unclear is whether those interests were pledged to WMI.
If yes, it's just a matter of waiting for the bankruptcy process to close, which should allow the respective Trustees to recontinue making distributions to the current holders of WMI Equity; ie, our Markers.
