Can we have concept artbooks..?

Seriously.. I need one. [Legends of League] or [The Art of League of Legends]. Yes, you guys are putting some of the concept arts online... but then why not make it a book?
Rito, everyone knows guys have so much artwork that could be shown.

P.S) Included a video so people can see what artbooks are (even though I doubt someone doesn't know what it is), and I don't understand a word the guy's saying but it's ok.
