I don't know how much pressure WN can bring on the NTSB to cover anything up. They will do their investigation and publish their findings.
If you look at their schedule,
Accident Investigations - NTSB - National Transportation Safety Board , the WN accident will probably be in published in January, followed by the UPS crash. I'm sure Christmas and New Year's have delayed the process some.
Just curious....why didn't you post this in the Rumors and News area where the WN 345 thread is located?
Happy New Year!
