Do you have any information you can share about the new McDonald criteria? When will the release occur? Will the new criteria, which apparently focus on preventing misdiagnosis, make it a more difficult, longer process for those "in limbo"?
New MAGNIMS consensus guidelines were published in March 2016 clarifying the MRI criteria that should be used to diagnose MS. This was meant to decrease over diagnosis of MS by inappropriate interpretation of the older MRI criteria. I am not aware of any other updated diagnostic guidelines at this time.
