Lot of good points. And really, I won't be surprised to learn that Beth is killing (ie ending development) the TES series, because quite frankly, while it has been a successful series, it doesn't rake in the CoD cash. At the end of the day, the RPG market is still a niche market, better suited to Indie developers.
Um are you sure you want to go out on a limb and say such a . . . Well, I'm not going to say "dumb" thing. Let's say misinformed, shall we?
The only reason CoD sells so much is: They pump them out with frightening regularity, each one basically the same. They don't take 5 years to develop a game. No siree.
They'll pump that bilge out and flog that dead horse until the end of time, and the crowd will still throw money at it. Because they think it's cool.
