Sony is going to make it's 3D firmware available in Japan, starting on Monday June 10th. Wipeout HD, Super Stardust HD and Pain are going to get updates. Motorstorm 2, might also have an update, but the only way you get it is by buying a specific Sony Bravia. Supposedly, the updates for Wipeout HD and Super Stardust HD are free, with Pain requiring a fee to unlock the 3D option. All of this info is for Japan, because I don't believe there has been an official announcement yet in the US. My guess, is that Sony will delay it till their e3 press conference, and then announce that it's available "Today", ala Steve Jobs.
It's expected that MLB 10: The Show, Little Big Planet and Killzone 2 will also have 3D firmware updates coming soon. It's going to be interesting to see how Sony handles this in the US, in terms of charging for specific updates, or bundling them only with certain Bravias. Personally, I think that would be really lame on their part, but you know they're going to do it.
As for Microsoft and 3D, the big problem is that hdmi is a requirement. There are an awful lot of Xbox 360 systems in the wild without an hdmi port. Still, Microsoft recently signed a deal with Samsung to supply 6 stereoscopic 3D games to Korea. No announcement was made stateside, but again, I think that with e3 so close, these companies would rather just save the announcement for e3, hoping that people didn't already hear about it elsewhere.
Is anybody going to try to jump on this bandwagon?
