It's odd that on the D3 homepage there wasn't a blog announcing its released. There was a preorder announcement, but Blizz is usually on top of this stuff.

The Book of Tyreal is available in limited distribution for some retailers (such as for the signing I mentioned earlier). However, the official street date is still October 29th. You'll see the book available at more retailers on that date. =)
