Earlier today, it was revealed that Robbie Bach and J Allard plan to step down from their responsibilities at Microsoft's Entertainment & Devices division. For Bach at least, the move appears to be related to the Xbox brand's next step beyond Project Natal.

Kotaku is reporting that Bach opted to step down because he could not commit to the additional three or more years needed to plan the future of the Xbox. Consequently, the 20-plus year veteran will be moving on this fall.

Allard has reportedly said that Microsoft has comprised roughly "95 percent" of his life in recent years, so he's stepping back to pursue other interests. Nevertheless, he will remain as an advisor to CEO Steve Ballmer while Bach plans to spend more time doing charitable work for the Boys & Girls Club of America.
