Sony just announced via its PS Blog that firmware 3.50 for PS3 will go live on September 21, giving PS3 owners the ability to playback 3D content on supported Blu-ray discs.

Stereoscopic 3D support for games went live in firmware 3.30. This update brings the PS3 up to speed with the latest in 3D ready standalone Blu-ray players, reinforcing Sony’s commitment towards longevity.

Also promised are “a few additional features.” There’s no word on what those might be yet. At the very least, this update is shaping to be more exciting than the jailbreak-killing security patch that was 3.42 for the select few that already dropped over a grand on a 3D-capable HDTV.
