Quick question about the Xbox 360 warranty.

[BottledSpringWater]

I have a Xbox 360 premium and it is about 1 year old now (still works). When my brother bought it at Best Buy, he bought it with 3 years Best Buy warranty. Later, Microsoft announced 3 years warranty on broken 360's since launch. What I'm trying to ask is:

Does the warranty adds up to 6 years?

 

Thanks,
