Yup, but the facts are that games really are getting more expensive and there's no denying that trend. I do think it absurd how much money some of these companies spend to make some of these games but the bigger the risk, the larger the reward... games like GTA and Modern Warfare are 100million+ games but they rake in the cash to make up for the cost.
Same goes for TOR, it's a high risk venture but enough people who have invested in its development, as inefficient as it may be, believe that the returns are going to be a lot more than what was put in.
On a more sobering note, Nintendo is one of the few developers who is actually capable of making a game for very cheap and then in the long run getting an extremely high return from their efforts... and there are many other companies like that, however BioWare, EA and LucasArts are not part of that thrifty developer circle at this stage... the truth is, there is a division happening with video games at the moment. You either make them for dirt cheap or you spend a HUUUUUGE mining dump truck full of cash worth of money on them... but these kinds of things are just trends and the video game industry is still very young. We can't really say that these trends will continue, they'll probably change as the industry evolves further.
