Thats what this Spencer guy says in the email:

Over the past 5-7 years, the AAA publishers have tried to use production scale as their new moat. Very few companies can afford to spend the $200M an Activision or Take 2 spend to put a title like Call of Duty or Red Dead Redemption on the shelf. These AAA publishers have, mostly, used this production scale to keep their top franchises in the top selling games each year. The issue these publishers have run into is these same production scale/cost approach hurts their ability to create new IP.
