This isn't really a question on my mind, but one that may go though some customers minds: Do the Studio Press Themes have WordPress hooks?

Are these theme for everyone or is there a knowledge requirement or limitations to how customized they can get without editing files?
Is he going to release a framework?
What kind of options should a theme have?
Where should theme developers draw the line between theme functions and plugins? How could themes be more customizable with plugins if they don't have or use the right WordPress hooks?
Is the GPL the right license? Do the general users get the GPL?
Are themes getting too complex for one person to manage? What are Brian's views on modular code? How does he manage upgrades or plan on managing upgrading dozens of themes when WordPress updates?
