The beta's going public on Jan4th giving anyone who wants a chance to try it out. Getting a chance to experience the game might get some to pull away from other games they're currently playing.
MAG is going to fit into the puzzle like every other new IP has to:
1) It all starts with the Publisher making sure the game is noticed.
2) Good Reviews for the more research driven buyers.
3) Word of mouth.
Does this answer your question? I'm getting the game ASAP btw.
