One of the other big hurdles that console devs face is time. That one would bite Blizzard in the ass pretty hard. You can't just sit on a console title and polish it until it meets a moving quality criteria.
Bottom line (as someone with extensive dev experience in both console and PC titles) is that both have their challenges. To make it sound like consoles are just inherently easier to develop for (or the reverse) is just ignorance speaking.
