Sony to launch PSP Go app store?

Ever since Apple launched the App store for the iPhone and iPod touch, every phone maker has been working on app stores for games and applications, even Nintendo launched the DSi Shop alongside the new DSi handheld console.
Since Sony’s upcoming PSP Go has 16 GB of built in memory, the possibility is certainly there of downloading smaller games that are made by indie developers and not published the regular way.
According to recent rumors, Sony is readying such a store, where indie developer will be able to publish their games (up to 100 MB), and either selling them or publishing them for free. It will also be possible to publish non-game applications.
