This document was 'leaked' several weeks to about a month ago. This document shows 'Titan' as the new MMO Blizzard will release in 4th quarter 2013. However, the authenticity of this document has been highly speculated. That being said, today Blizzard confirmed 'Titan' as the name for the new MMO they are developing. For 'recruiting reasons'. This sparks the question that this document could in fact be legit.
I personally think it is... the dates are logical and make sense. That being said, we all know Blizzard is notorious for delays, so expect months (and potentially even years) added on to these expectations.
Other than that, no further details were released. Just thought I'd share with any of you gamers out there.
