Made a Little test between Pulse 1 and 2, and yes there are differences, but it's mainly in the resonance and crossmod parts as far as I can hear... different, but close... more on some presets than others.
You can hear the comparison here;

The first machine is Pulse 2, then Pulse 1 right after.
I've not yet decided if I'll sell my Pulse 1... need to do some more testing to see how close they can get in comparison... the demo was made by simply sending Pulse 1 SysEx directly to the Pulse 2, so maybe some tweaking can make it even more close in comparison on the presets that sound most different.
