No one knows if it will be faster...they are just saying it will be...but I don't have high hopes that it will reduce wait time too much in the long run, since everyone and their cousin in going to put in one or several eForm 4's...and I'm sure the ATF will use this a justification to reduce the number of examiners, etc.
I'm just waiting for the other boot to drop...they give us a little thing so they can take away a big thing.
