I'm wondering whether besides collecting the typical tracking information (IP + cookies) google has already implemented browser fingerprinting? I read sometime not long ago about it being a hypothetical future method for tracking and identifying google users and would like to know if it's already in use officially?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
The implementation of browser fingerprinting is known and trivial. Most of it is just reading the headers from the HTTP request. Whether Google implemented it or not is irrelevant, since they could implement something to the same effect in a matter of a few days at most. What matters is whether they deployed such a system -- and, "officially", they did not.
