My opinion:
Nord Drum maybe be better as an addition to an acoustic drum, where you could add some different drum sounds (shaker, etc...)
Nord Piano 2 will be killing a lot other stage pianos from other brands with this sample feature, maybe some people that only need sounds to play at home will buy it instead of an NE3 or NS2.
Nord C2D is much more old school now, I like the Led thing, that you can see were each bar is at any preset, but for JAM and Gospel, I guess C2D is better this way
And I thing an Keyboad setup with C2D and NP2 will be a very nice one. Maybe Add another synth (NL,NW, etc...) and you have all you need.

I guess the next thing will be an Nord Stage 2D ? or NE3D?
