Pricing: We will see fewer $60 titles and more at 30-50. COD and the like will keep getting an additional $60 in DLC for many of its customers. I don't think they can or should go for higher initial cost outside of special editions.
Sony PS4 Event: I thought it was one of the best ever. Mark Cerny has been in charge of the platform for 5 years already. This means the special stuff they were talking about probably already works if not yet on the final hardware. Lots of actual in-engine game footage 9 months out from release. More solid and interesting stuff rather than flash and fantasy. Seems to be lots of people in the game and tech industry who say something similar. So maybe a great announcement for those who care and bland for the larger audience?
