It's slight, but noticeable. The 15 Pro was 187g and felt much lighter than the 14 Pro, it's a shame they added more weight on the 16.

Well the 16 Pro has a 0.2" larger screen and large dimensions than the 14 pro and 15 pro.

Also the 17 Pro will now be aluminum which is even lighter than titanium, so it should be a bit lighter than the 16 Pro I think.
