Prototype Demo Available Early Next Month?

We now know that Prototype will be released early June, but we now have reports coming in that the demo will be available on the PlayStation Network (PC & Xbox 360 Live also) in the first couple of weeks next month.
The Demo is likely to feature the first level of the game and might include a mini level to go with it. The key aspect of the game is obviously 'diguise and destroy', you will be able to shapeshift into almost everything and the game is promised to be a huge hit. You will be able to run up walls, fly, a destroy almost anything.
