Apple Keynote Leak?

Geeking around on the Tubes today, I came across this little nugget.

Highlights include a system for users to create and sell iphone apps, a new Macbook, and the ability to download Youtube clips in iTunes (for free, I'm assuming).

I can't vouch for whether this is the real deal or not, but if you're like me, you're anxiously awaiting the next slice of my free time that I can willingly hand over to my iphone.
