Microsoft's Aaron Greenberg was asked for his "official" response to said study; the entire quote is viewable below:

Thanks for your note.
 
There have been a lot of external “studies” on the failure rates of all consoles, not just the Xbox, and the numbers have been all over the map.  The only people that know the actual numbers work for Microsoft, and the numbers are not something Microsoft or any other company would typically disclose for competitive reasons.  What I do know is that more than two years ago, Microsoft addressed this issue by extending the warranty to three years for consoles with three flashing red lights. More recently, we extended this coverage to include the E74 error message as well. We continuously invest resources to improve the reliability of our products, and we believe that this issue is largely behind us. Xbox 360 is pleased to maintain the title of “most played console,” and is grateful to our loyal and engaged customers, the majority of whom continue to have a terrific gaming and entertainment experience.

The failure rate is over 9000!!!!!

They covered their asses good with that 3 years warranty. Fanboys think it's service, but in reality it is just meant to protect them from anyone threatening with a lawsuit.

The Falcon and Jasper versions of the 360 slowly decreased the RROD rates. The 3 year warranty just kept the people loyal.
