We know practically nothing about Titan. All we know is that it's an MMO in development by Blizzard.
Off of that fact and that fact only, when this new MMO (most likely with an equal subscription fee to World of Warcraft) decides to release, will you switch from World of Warcraft to it?
I will move on because it will be by Blizzard. Any MMO made by another company I either play on the side or don't play at all, but the fact that it will be made by Blizzard and that it is an MMO is enough for me to guarantee that I will switch to it from WoW when it releases (assuming it has a subscription fee).
