Sorry, but no.
I agree with your assessment of the AAA industry, but while I think Levine has every right to leave in search of greener pastures, I think you and many people are missing the point of his actions and forgetting the other side; the real victims of personalities closing mega-studios in search to narrow their reach are not the gamers that want more high budget RPG and less modern shooters, its the hundreds of talented people that busted their asses to give us one of the best games of last year, and collaborated a whole lot to its success, even when not in the spotlight, finding themselves without a job one day because their master and commander decided to jump ship and left them with nothing but an empty office and a few lines in a resume.
"Irrational Games has been sunk, but Ken Levine is still here"... I am sure its a big consolation for those people. When Romero and Carmack left Id, it was still there the next day. The same with Jaffe and Santa Monica or Bleszinski and Epic... This here is closer to "I'm going to take my ball and go home!". Of course, I believe Levine is a very talented man and I will eagerly wait for his next work, but I don't think this is a time for celebration, as much as I don't believe its a lost for the industry.
