This is not a PSP2, this is merely the continuation of Sony's move towards simply utilizing the best of Android and PSN/Playstation brands.
Basically all of their portable devices will have strong gaming applications running on Android with a hook into PSN. Gives them a far larger market across all products and adds a good feature set into every existing product they normally sell.
They will put out a more traditional PSP2 that takes media at some point.
... and its confirmed fake, but my logic above still fits as my opinion on Sony's path anyways.
