Latest version of our component architecture research (from September 2012) is now up and available at the 360idev videos site.
From the presentation abstract:
This talk is a follow up to my 2011 360idev talk on component architectures for iOS games. It includes specific in-the-field post mortems and performance analysis from the implementation of a variety of component systems, implemented by myself and others (including other 360idev regulars).
The performance measurement elements are applicable to all architectures and the post mortem information is full of technical goodies about iOS implementation detail and nuance.
