[Update] Inside Dynamics AX 2012 Book?

Wondering if anyone knows when will Microsoft release "Inside Dynamics AX 2012" Book/Ebook? If so, please post a comment here.

We had versions for AX 2009 and 4.0
AX 2009 http://www.amazon.com/Inside-Microsoft-Dynamics%C2%AE-AX-2009/dp/0735626456
AX 4.0 http://www.amazon.com/gp/product/0735622574?ie=UTF8&tag=micstosit-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=0735622574

If I come across any news, I will post an update here.

Update #1


Thanks to Harish who sent me a tweet reg this. I can understand becoz of the vast number of new features, it would take some time for the book to hit the market.
