The typical review time for a 1st decision in my field is 4-6 weeks. It has been nearly 12 weeks since initial submission of a piece of work by a student who just graduated and will leave the lab in about a month. The problem now is what if the reviewers ask for additional experiments to be performed, but the student who actually knows how to perform them has already left the lab?
Would it be okay to ask the editor to release any referee reports already completed while they wait for a final decision? This could help us get a jump start on any required additional experiments and complete the work before the student leaves for good. Obviously it's unusual, but my thinking is that we'll see the referee reports eventually anyways, so would there be any harm in seeing them a few weeks in advance?
