Shakespeare's Will Isn't Already Online?

I just learned that one of the Ancestry.com sites (the UK version) is going to be putting a million documents up online, including William Shakespeare's.

But ... isn't it already online?

I suppose that what they mean is that this will be a complete scan of the original document.  All I can find are pieces, which I assume have either been released over time for press/media purposes or perhaps even created by individuals with access to the document itself?  I'm unsure where the original lives right now.  There's a few hundred First Folios in existence, but only one original will.

Is there anything that we can learn from this new version that's coming online, or is it entirely for the publicity?
