I was truly saddened to hear of Monty Oum's passing. He was an incredibly talented person. I loved his work especially Red Vs. Blue and have really been enjoying RWBY. My heart goes out to his family and friends. It's truly a sad thing.
Rooster Teeth posted a very touching announcement about it which you can read here: http://roosterteeth.com/members/journal/entry.php?id=3302319
R.I.P. Monty Oum. The world seems a little less brighter without you in it. You will be missed.
