Not sure if you saw the update on the Yahoo board but Dr. BP was contacted by two different individuals and both received a reply that last week he submitted edits along with additional data that they had requested. So the process is in progress but no telling how many revisions it will take. Having done this before there are times when it goes quicker then you think and times where it drags out. Very much dependent on the reviewers, their schedules, how timely they get back to you, etc. It is a good sign that they are going back and forth though. That means the journal thinks it is definitely worth their reviewers' time and the reviewers are intrigued enough to ask for more information/edits.
