FWIW, the chainring tooth thickness has not been changed for a very long time. It should be the same on 8,9 and 10 speed rings and even most 7 speed.

The new Campy 11 speed chainring teeth are .1mm thinner than the 10 speed teeth. The distance between the inner plates of the chain is also slightly narrower, but it still works adequately with 10 speed rings.

Although all modern 10 speed chain are 5.9mm across the outer plates, they are not all the same across the inner plates. Campy and SRAM are about .1mm thinner and this affects the fit of master links is you don't use the proper model.
