This all depends on if BioWare retains enough creative control to do their job or not.
EA's job is to make money, not necessarily make great games. If a good game with adequate production time sells as many units as a great game with a longer production time, they're going to go with the one that makes the same money but is made in less time. If BioWare can convince them that an excellent quality product meets a niche in the market, then it might fly. Otherwise, hopefully other studios will step up into the gap that BioWare will leave behind.
