Came back to see what kind of crazy conjecture both sides have come up with in this thread. Looks to be the same blah, blah, blah about theoretical performance and the one developer said BS. You can NOT definitively say anything because it is all guess work by ANYONE. Devkits are not final hardware, and mocking up similar spec PC's is not an answer either. Both systems have been customized in ways that we may never really know without actual parts designs in hand. It seems obvious from the generic info provided to date, that the PS4 is more powerful somehow. The key word is "seems". Like I and many others have stated, you will definitely have to wait until a minimum of after launch to even have a partial understanding of the true power of each system.
