The problem with time jumps is that they so rarely pay-off, at least in my opinion. Either we get things like DC's "One Year Later," which presented some change in the status quo (though things like Aquaman being dead and replaced eventually reset themselves). The problem came when they decided to reveal some of what happened in the missing year for the characters not highlighted in 52, which lead to some hasty plot points shoehorned into World War III or problems like when, exactly, Jim Gordon became the Commissioner again. In the case of the former, apparently a good majority of the changes we saw in OYL happened during World War III, which took place only a few weeks before they point in which we saw the characters in OYL initially.
The other problem is, as Praetor_Shinzon said, a reset. While I hope not, I fully expect something to be revealed or happen that the characters realize must be fixed, leading them to send someone "Days of Future Past" style to the past to fix before it happens, leaving all of what we saw previously wiped out, and the status quo set back to the end of the 1st season.
