With the new regs only in year 2, I'd be surprised if any changes are made to season dates/length before 2017.
The only "season" I can see that might be "changed" is the bonus antlerless season. And that's only because that season is valid only in counties with a 4 or higher bonus antlerless quota permits available. So if deer numbers drop too much, the DNR could just drop counties to a 3 (or less) and the season doesn't happen.
No muss, no fuss. No having to go through the mess they did just a few years back.
