I don't know if it could be considered a wow killer, since it's made by the same company. I would think of it more as a wow successor. Plus, wow is really old now, so it's kind of on its way out anyway. From what I understand, Titan isn't based on any existing Blizzard universe, so it probably isn't wow 2 or world of starcraft. Although, they may have said that just to throw us off the scent. All we really know is that it's an mmo and they are using a lot of the same people who first brought wow to life. I'm excited about it because blizzard makes great games, but it's hard to keep up with all the mmos out there. I've only played a fraction of them because I don't have the time to invest. It will also be difficult for blizzard if wow is still active when titan is released. Many people still play wow just for the nostalgia (myself included).
