What happened to Riccos Book?

What happened to "How to Win a Street Fight: The Life and Lessons of an Ultimate Fighting Champion" by Ricco Rodriguez? I placed a pre-order on this book on 3rd of January and it still hasn't been released. On Amazon the original release date was sometime in Feburary now it is May! What is the deal with this book? I might cancel the pre order!

Now it is May? Where do you live?

In Australia. It doesn't matter where I live it hasn't been released at all yet. I just checked Amazon before.

Oh I meant the release date has been pushed back to May!
