Well - one can definately see from the WMI/JPM/FDIC/HF perspective WHY they might want the expert testimony of these two individuals NOT to be heard.
My guess - is (at the least) their analyses indicate how horribly NEWCO's post-emergence value has been sold short by these parties. At worst - their testimony indicates how WMI/JPM/FDIC (via our 'buddy' Rosen) have attempted to run a fraud against us and this court.
