[QUOTE=Instant] Unlike blender Construct is ridiculously easy to pick up , so it'd be absolutely pointless to make DVDs / Books , especially for 30 dollars.[/QUOTE]
I don't think a Construct book or DVD would be pointless at all since the goal would be to teach someone a new skill in a fundamental way that they wouldn't have gotten otherwise. Since people tend to learn and understand in different ways and at different paces, even Construct would benefit from these types of resources, and certainly other programs of its type have had them. I'd also like to point out that this style of event-based game development is not for everyone, and even the most experienced and/or talented programmers versed in other programming methods may and do find these types of programs frustrating at times. So difficulty or ease of use really is a matter of personal comfortability and expectation.
Aside from the HobbyPress book on Construct which I haven't read (and can't vouch for whether the book is good or bad), So far there haven't been any other worthwhile companies of any professional stature pushing towards a good, deep, Construct resource, but I'm sure someone will step up in the future.
