I'd say as long as they keep updating the game, bring in new content it should hold. MOBA especially for the home console is a rare-ish type game, and vastly different than the normal games we get on home consoles. So there are new people everywhere. If anything they should use The Hobbit as a sort of stepping stone to advertise the game.
I walk alone in the universe as the last of The Time Lords!
GOME is my first MOBA experience. I hope that it flourishes and earns a community. I played my first two matches last night and it was a blast even though my team lost both times. I'd like to see it grow larger.
