109w ago - While it's not surprising news, today Sony announced that PlayStation Vita owners will be able to download a UMD Passport Registration Application for UMD support on PS Vita consoles, which uses both cartridges and digital downloads according to the official specs.
To quote from Kotaku (linked above): "Starting Dec. 6, the UMD Passport service will start in Japan. Here's how it works: Download a free app called "UMD Registration Application". After that, enter your UMD game disc into your PSP, and according to the on-screen prompts, register your UMD via your PSN Account. The UMD will then be available for purchase.
Once the PS Vita is released in Japan on Dec. 17, you can then download the title on your new Sony handheld. According to Sony, the games will be available at an "agreeable price".
Currently, 40 game companies are offering 200 UMD titles as part of Sony's UMD Passport program. The digital versions of the games are priced anywhere between ¥100 (US$1.29) to ¥2,400 ($31).
