Unless BioWare surprises everyone and comes out with a Mass Effect MMO in the next 5-10 years.
Ha. Who am I kidding? That will never happen, but a huge fan could hope for a MMO in that universe, developed and launched without pressure from EA or whatever. Unlike the pressure to release SWToR.
And I will keep hoping.
Yes, this was random and out-of-the-blue, because there have been, as I recall, no talks about a ME MMO whatsoever. Just saying that if it were ever to be made, and well-developed/finished, I would leave WoW for it forever, unless they really go the SWToR way again.
