Looks as though Verizon will soon be testing some new OS updates for the BlackBerry Bold 9930 and BlackBerry Curve 9370. These updates will of course be BlackBerry 7.1 updates and will be released intially via OTA. According to the leaked documentation testing will take place on the week of April 24 and run until May 15, after which time, upon approval they'll be pushed out to consumers. That is, pending any further changes. The dates are always subject to change. Sadly, it doesn't state what OS' are that eventually be released but knowing they're coming is half the battle plus, we could always take a wild guess based off the most recent OS leaks.
