Re-evaluating item stat values
Blizzard is looking at the value of sockets on items (currently, the value per socket is slightly higher on higher quality items) and standardizing it throughout the game in an upcoming (but unspecified) content patch. In addition to this, they're also going to reviewing the expansion armor sets -- Drysc says it's not the intent for higher tier sets to be poorer quality or side-grades to previous sets, and that some sets may see changes in the future.
While Drysc seems to be talking about future changes, some re-evaluation of item values seems to have already happened in patch 2.0.10, however. This list of undocumented patch changes, compiled by Ramiel, contains numerous item tweaks -- some good and some not so good.
