It makes sense, I imagine working in the industry must be crazy amounts of tough. They have such a limited amount of time to learn the ins and outs of the system and make it work to their advantage. I feel that next gen may be coming way too soon. There's still a lot that developers can do with the technology we have now and yet everyone's in a hurry to move forward without taking the time to draw out what we have already.
The schedule to finish games is very harsh. there are similar nightmare stories from former staff of every Rockstar game made this gen. Workers leave because its too stressful. 12 hour days and working on weekends as well. I'd go crazy. I'm glad I gave up on my dream to be a game developer. its not as fun as i originally though.
