I too recall hearing this, but email tracking definitely still works in Gmail, and Google, being the advertising and marketing king, has no incentive to upset their actual customers by defeating email tracking. (In fact, AMP4Email, a.k.a. "Dynamic Email", will probably make this even worse.) I suspect the thing we heard about means Gmail is messing up the IP address/location tracking aspect of a tracking pixel, but still loading it on email opens. The bargain of "we'll hide the user's IP, but still allow you to track their behavior" sounds like the devil's bargain I'm used to from them.
