There is a good chance that they are the same. Maybe binned a little higher or driven at like 1.1W instead of 1W. But they did say they tweaked the frequency a bit. And there may even be some better trinkets inside the projector as well. Possibly better lenses, stronger LED, ect.
^ This, even if the wavelength doesn't change, if they figured out a way to correct the square shape with just one lens then it'd be worth it.
