Old news. We talked about this last month when Gearwrench had the regular 3/8 ratchet with 84 teeth on display at the SEMA show in Vegas.
Unlike the Craftsman premium, the Gearwrench versions will use the thin steel gear cover with snap ring instead of the thicker steel plate with two screws.
84 teeth will become the Gearwrench ratchet standard next year across the whole line in 1/4, 3/8, and 1/2 drive to include flex head and comfort grip models.

It's just a variation on a theme. If you open up a Gearwrench, Armstrong Maxx, or Matco ratchet with 60, 84, or 88 teeth, it's the same design with the multitoothed floating pawl avalible in 3 tooth sizes..
