Dewalt New Concrete Saw DCS692

Does anyone know any details about the new DCS692 Concrete Saw and how it differs from the existing DCS690?

My understanding is that there are two differences:

  1. the lid for the battery compartment on the 692 is taller, which allows the use of 15ah batteries.
  2. the 692 has a wireless connection feature which can turn on a dust collector remotely.
    I believe the rest of the tool to be otherwise identical, I’ve seen some promo material for this saw while I was looking for information about other tools and none of it mentioned anything about improved power or runtime compared to the previous model so I assume the motor and everything else inside the saw is the same as the 690.

If you don’t ned the wireless connection I would go with the first model
