In Japan at least, Andriasang reports, Wipeout HD, Pain and Super Stardust HD will be updated on the same day, with Pain requiring a ¥300 charge to unlock a 3D mode. The news follows Sony's announcement last week that Killzone 3 will be playable in 3D.
Sony has invited members of the UK media to a "Sony 3D" briefing on the same day, presumably to usher in the update.
The Japan-based news site also said that Sony plans on updating PS3's firmware to support 3D Blu-ray later this year.
