2011 Tundra reduced max tow capacity, options?

I read somewhere that Toyota volunteered to began using a new method of setting tow weights that lower the weight some and that other makes will be required to use the same method soon. I have a 2010 Tundra double cab rated at 10500 but the same truck new is less. I tow a Rockwood 2904SS 33' loaded weight up to 7600 lb. Tows with no problem.
