Well it seems today that a beta tester for one of these groups was not completely careful, and leaked a video showing him running psp isos on a Vita (video below).
The video shows the tester (who is possibly Chinese) running isos for Metal Gear Solid : Peace Walker and Shining Blade through a (PSP) kernel exploit.
I have been told that the initial video has since then been removed which is why I’m thinking of a beta-tester mistake, but that was probably too late and the video got copied to other networks such as youtube.
