This is some really interesting stuff. Watching the videos as they've been released has provided some crazy insight to the world of video game development. In this video Greg Rice said that at one point during the Iron Brigade development a guy came down from Microsoft and said that they were going to cancel the game if they couldn't get it out by a certain point in time. Shit like this probably happens all of the time, the difference is we actually get to see it unfold.
I quit WoW at the end of December. I was having some fun PvPing, but because I had started later than everyone else I was woefully undergeared so it wasn't as much fun. LFR also wasn't very enjoyable for reasons similar to what you posted. The new expansion was fun for a while, but the game just doesn't grab me like it did back in vanilla.
