The only issue that I see is that there is no Hammond simulations, but I manage to have the wave 2 midi'd to my NS3 for the piano-lower/hammond-upper situation.
I love the Wave 2 because it has 4 splits/layers (enough for me) and has the same structure that I understand from Nord. I used to have a Motif/Kurzweil and I manage to do what I want, but if I needed to make new sounds/modification I almost have to go reverse-engineer what I did

The simplicity of the Wave 2 (and also enough depth for more complex things) together with the sample-loading option and the Nord Sample Editor makes it very easy to transfer samples from VST, other synths, samples from internet...
For live usage more than good enough, very light, very quick modification during rehearsals/live.
There are also many virtual analog sounds.
I'm sure the Roland/Korg/Yamaha direction will also give similar or perhaps even better results, for me the simplicity wins so i can focus on playing
good luck with your setup!
