depends where you are in the world. Valve may have sent an older version to whomever that was, you need to measure the stick to see if you got the updated version.

It took over 6 months of brutal everyday use for my release day knuckles to develop a drift issue in the left stick - so it does happen but not to everyone and not at the same rate. 
There seems to be a flaw in some, but not all joystick encoders and it does appear they're working on it.
