Normally, Iíd would say you are correct, but BioWare isnít the normal developer. They planned Mass Effect as a trilogy and even hinted as much before the sales figures were fully known. It may be a product of the own success. So far they have been pretty successful both in sales and critically. One day that past success is liable to end up biting them in the butt when a game does not live up to what people expect from BioWare. So far, it has not happened.
