It could be: Sony trying to get everyone to update to 1.51 since they are aware of the exploit in 1.32 (Also aware that most of us are not uptading our firmware) . Which in turnes means this video is fake.
It could be: The video is real, the exploit is real and present in the 1.51 software. Meaning its safe to upgrade. However this exploit might never be released and therefor if paradox wont work on 1.51 we are all out of luck.
It could be: Everything is fake. Eventualy we will all realise this and update to play mortal kombat online.
At the moment no one knows. Paradox is dropping hints here and there. He is getting pressure from all of us to release something but if he wants world wide support then he will have to wait untill the world gets the PS3. This makes more sense to me than anything. Everyone here can be patient. A working loader just 4 months after the release of the system is awesome. Just think, in a year no one will care that we waited at all. We will be talking about hacked firmware, not working loaders.
Quite honestly If I lived in the UK I would be upset if the loader came out now and was patched before the UK launch hence keeping me from running it out of the box.
I do wish paradox would release a small video that shows their work in action. Not giving away any secrets but showing the loader working on more than one game. Also it would be nice to hear from them if the loader works on the latest firmware confirmed.
