The website Average App Store Review Times collects reports
from developers who tweet about how long their apps spend in
Apple’s approval queues. Based on nearly 70 reports, the site
puts the average review time at 27 days for the past month, and
the trend line shows that reviews are slowing down, not
speeding up. (The same site reports the average iOS App Store
review time at seven days.)
Hopefully just a hiccup from the rush of iOS 6 and iPhone 5 compatibility updates.
