Really no way to tell yet. When they get to the mid-July submissions, there will be two new issues to contend with:
-The huge glut of forms sent in that last week or two before 41F went into effect. This will cause a sudden choke point.
-Dealing with the new rules with post-41F submissions. The added steps to now also perform background checks with trusts, most with multiple people to do them on. The headaches with having to determine who is/isn't a responsible person by thoroughly reading each unique trust, and then dealing with the inevitable increase in denials and/or possible error letters to correct forms not submitted correctly under the new rules, and so on.
All of this will likely bump the wait times up very quickly, and until the dust settles and we see where it all lands we won't really know what to predict.
