Wow, 4th Edition's comming.. (from Amazon)

Hi everyone, i was waiting for this book so long time, is there any way to buy PDF version?

Is there an updated release date of when the book will be available?

Amazon is now showing October 19

As noted in

an eBook version does exist at this moment so discussion can properly move to the 4th edition forum at this point.

I just bought the kindle version of 4th Edition. Could you tell me where to download the sample code in the book? Please email as I don’t log in the forum often.
Thanks much
