I see a $400 price tag for the basic and a $450-$500 price tag for the premium, so $100 cheaper than the PS3 at launch. Because of the falling Blu-ray, HDD, and RAM prices, Sony will be able to put in a really good CPU/APU and GPU and still either break even or make a very small loss on the HW.

You're very wrong if you think the PS3 launching for $200 more than the 360 had little to do with the 360's success. Do you honestly think that if the PS3 had launched at only $50 more than the 360, as well as not having weaker ports for the first two years, MS would have even stood a chance? Even when the RROD hit? Unfortunately for MS, it looks like the PS4 is going to launch at nearly the same price, at nearly the same time, and have the same support. This going to lead to EU and Japan latching onto the PS much quicker then the current gen. And America may not be there to save the NeXbox.
