It has been stated by Blizzard that there will be ladder resets every 6th month:

We've heard you, so this is a one week warning that the Diablo II ladder will reset next Monday, March 28. We generally prefer to provide a two week warning for the case of resets, but to hit the exact 6 month mark we feel one week is sufficient this time.
The current ladder reset will happen May 27th 2014 - the next one is predicted to land between late November and early December 2014.
