The sampling features will be implemented in software.
The last update, 2.0, gave the Triton sampler time slicing and time stretching.
Your best bet is to head to your local synth dealer and to play around with the Triton, an 88, and an EMU sampler.
But you will be hard pressed to find better strings. Expansion Board 2 for Triton adds even better strings, if that is even possible.
