I disagree with that. Bioware/EA has put a lot of money into this game. If this game were to fail, that would show the other companies that the MMO market is dead, and that they should shift their resources elsewhere.
Games, like other things, evolve over time. You just can't take a piece of wood, and turn it into a jet aircraft. There must be a singular idea, that changes over time.
Take the MMO universe. It changed from the simple MUD (Multi-User Dungeon), to the more complex version of Everquest. From there games like WoW, SWG, EQ2, etc. sought to improve on the original idea, not spanning too far from its roots. Currently, we have TOR, and soon after we will have GW2 and Dark Millennium.
These games will still have the original mold of the MMO in mind, but will expand on it in order to create diversity within the MMO genre.
In short, games evolve, and if a certain step fails, it will stunt the growth of the genre as a whole.
