Some info:

Next Minor PC Patch: Patch 2.0.5
The next Diablo III PC / Mac patch will be a minor bug fix and game balance patch, titled Patch 2.0.5. Here are details on the changes and fixes that are expected for that patch.
There may be additional minor patches in the near future (like a patch 2.0.6), if they are needed to deal with more bugs and balance concerns, before the major patch 2.1 arrives in a couple of months.
Patch 2.0.5 is very near release, and could arrive on any Tuesday. If it is fully ready, it could go live during the server maintenance this Tuesday, April 29.

Is there any chance the maintenance end earlier ? my hand itch already and i cannot brain what i should do now.
