Sony is betting big on 3D, bigger than anyone else. And they’re putting their money where their mouths are — 20 of Sony’s internal titles will have added 3D feature, while another 30 from third party developers will feature 3D. According to Sony’s Mick Hocking:

Overall we have more than fifty titles currently being converted into 3D, and this number if growing fast. Some of them are massive names. That’s a really, really good sign that the industry is behind our unique message that 3D is a key element in the future of home consoles.

According to Hocking, who spoke to Develop, adding 3D costs just 2% more on the budget. Which is remarkably low, maybe too low.

We previously reported that most 3D games on the PS3 will be in 720p, and not it turns out that all games on the PS3 which feature 3D tech will be limited to 720p. It’s understandable, as on a technical level, 3D requires twice the amount of frames, so you end up with two 720p images, one for each eye. However, it seems silly to limit 3D games to 720p, as we’re sure some developers out there would be able to squeeze two, 1080p images out of the PS3. The PS3 is already capable of displaying 1080p 3D images, as 3D Blu-ray films will be watchable on the console later this year.

Sony has announced that the upcoming PS3 3D update has been delayed a bit and will instead be released this September. Furthermore, Sony revealed that it will also support YouTube’s 3D implementation, which should be available within the next 12 months. Yep, 3D is coming hard. At least according to Sony.

Sony has announced that a PS3 update scheduled for today will bring Stereoscopic 3D to the console. The games supported so far are WipEout HD, PAIN, Super Stardust HD and MotorStorm: Pacific Rift. Of course, you’ll need a 3D ready TV and some goggles to experience the new dimension.

Sony is pushing 3D gaming on the PS3, and 3D in general, pretty hard. However, according to a recent statement from Sony’s Ian Bickerstaff, who revealed that the 3D games showcased at GCD 2010 were downgraded from 1080p to 720p, games like WipeOut. The PS3 is not powerful enough — or optimized — to project two different 1080p frames to each eye to create a 3D effect. Instead, two 720 frames are used.

For native 720p games like MotorStorm, the 3D version was scaled down even more, to standard-def graphics. For Motorstorm, the developers used the technology from the split screen mode in the game, which renders two different environments at the same time. Motorstorm in 3D then projects two 480p images for the left and right eye.

Sony expects to optimize the technology to offer a full 1080p resolution, but there’s a lot of optimization to be done, since the games will have to deliver twice the amount of frames per second to be in 3D and in the same resolution.

Whether Sony can do this without sacrificing image quality remains to be unknown. One solution would be to have the regular, 2D mode with image quality running at the highest setting, and when 3D is used, image quality would be scaled back in order to provide twice the amount of frames.
