They're being so vague with the numbers that I really doubt how mature any of this is. Given some of the examples (photos, music, War & Peace) I'm guessing 3TB or so, but it's a fluff article, so who knows.
Just out of curiosity, I calculated that the article's (War and Peace * 875,000) claim would net you less than 1TB of storage space (~973GB), assuming it was GZipped (and ~3x that if not).
The most concrete number we have is from another article (also on an official Microsoft page) that claims it's upwards of 7TB.
