Another "Music of League of Legends" Album?

When the first "Music of League of Legends" album was released, I was instantly hooked on it. I'm very impressed with the music Riot produces for League, be it for Champions or special events, and I love to listen to those themes. Hearing some brand new pieces (like "Tiny Masterpiece of Evil") alongside Champion themes was particularly nice.

I'm going to assume that Riot plans on releasing another collection of music sometime in the future, given that the first album was Volume 1. My question to them is this: Do you have an idea when (if) Volume 2 will be released? I may be the only one wondering about this, but regardless, I'm interested to see if it's in the works.
