Via the Official PlayStation Blog 3D support is to be added to our PS3’s on 9/21 taking us up to firmware version 3.5.

I’m sure there will be some secret hidden tidbits in there to further block piracy 🙂

Edit:

In addition to Blu-Ray 3D support, 3.5 will also add Facebook support to see and use your game information and the ability to report unwanted friend messages.
