Android has gone through quite a few changes during its short 6 years of life. The Android that drives most of the world's smartphones of today would be almost unrecognizable to what was launched in late 2008.

Update: OnePlus claims the Indian version of the OnePlus One will ship with CyanogenMod. However, OnePlus plans to eventually shift as many Indian OPO owners as possible to the company's own Android ROM early next year, though the OPO will continue to receive worldwide support from CyanogenMod for the time being.
Update 2: Cyanogen Inc. has clarified how updates will work. If a device is shipped with CM, it gets updates even if it's sold in India.
