We should see the 4680 batteries in the S this year. With the range going up to 520 miles for the S, with increases in performance.No, it has progressed to about 300 W*h/kg with Tesla's 4680 battery, and, with further improvements, may exceed 400 W*h/kg. And there are many batteries in labs that far exceed that density. Some by as much as a factor of 3. But, as Musk has stated, what works in the lab is a long way from being possible to manufacture at a reasonable cost in industrial quantities.
When the 4680 battery goes on sale and is used in a real-world environment we will see real efficency, right now it's marketing. And in laboratories, there are many concepts of batteries with a density of energy even more than 1 kWh / kg (i worked in one of these laboratories), but when these batteries go out of laboratory conditions into real life, many problems arise that prevent the use of these batteries.
