Those of us, looking forward to 1080p 3D games will be disappointed, as it appears we wont be getting them, games that are natively 1080p, will have a downscaled 3D version, this problem isnt a hardware limitation, it is due to Sony's guidelines on 3D games.
Sony representative Simon Benson confirmed this during the Develop conference, here is a quote of what he said:

Sony's Simon Benson explained during a demo of the technology at the conference. While the PS3 is capable of displaying a 1080p 3D image -- indeed, it will support 3D Blu-Ray movies at that resolution later this year -- Benson said upping the resolution comes at the expense of the silky-smooth 60 frames per second available at 720p (Blu-Ray movies run at 24 frames per second). Benson said that a "more cinematic game" might be well-suited for the lower frame rate and higher resolution, but that Sony's current guidelines for 3D games wouldn't allow for such a setting.
The effects of this policy are probably unnoticeable to most gamers. Benson said that, in 3D, even trained computer graphics artists could barely tell the difference between the resolutions.
