I didn't see any further clarification in the document, but I'd
specifically like to know if the said organization has to be external to
the group responsible for development of the custom code. I realize that
would be best practice anyway (just like development and QA groups
should be distinct) but the realities of business may not always
encourage that.
On the firewall side... will there be some kind of validation process, I
wonder, to certify that a specific product / solution meets the PCI
requirements?
I suppose that's why we have until June 2008 for this to be fleshed out
more. Definitely a step in the right direction however.

Before actually reading the PDF, I immediately want to ask:
1. What are the criteria for an "organization that specializes in
application security"?
2. What is considered an application layer firewall?
Maybe these questions are answered in the document.

Under the new requirements, applications processing cardholder
information MUST get either a code review or a web app firewall.
The language isn’t exactly clear about what happens in 2008.

6.5 Develop all web applications based on secure coding guidelines
such as the Open Web Application Security Project guidelines.
Review custom application code to identify coding vulnerabilities.
Cover prevention of common coding vulnerabilities in software
development processes, to include the following:
6.5.1 Unvalidated input
6.5.2 Broken access control (for example, malicious use of user IDs)
6.5.3 Broken authentication and session management (use of account
credentials and session cookies)
6.5.4 Cross-site scripting (XSS) attacks
6.5.5 Buffer overflows
6.5.6 Injection flaws (for example, structured query language
(SQL) injection)
6.5.7 Improper error handling
6.5.8 Insecure storage
6.5.9 Denial of service
6.5.10 Insecure configuration management
6.6 Ensure that all web-facing applications are protected against
known attacks by applying either of the following methods:
. Having all custom application code reviewed for common
vulnerabilities by an organization that specializes in application
security . Installing an application layer firewall in front of
web-facing applications.
Note: This method is considered a best practice until June 30,
2008, after which it becomes a requirement.
