I have the same problem if its any consolation, and in my case, it might have been longer than 2 months..

I actually started hammering away at their online contact form for app reviews. After I did that suddenly a few days later it went to "In Review" and then "Preparing for the App Store".

If you have a serious bug fix, there is actually an expedited review service which has a theoretical turn around time of 2 days. I used it twice and the first response was within 12 hours and the second time within 48 hours.
