How common or uncommon is it for a new arranger model to look exactly like the previous model? If that’s the case with the S970 vs the S950, where’s the difference? Will it be the sound, styles, voices, features, what? And, will this difference be enough to justify the obligatory price increase that’s most likely? I’ve been trading-up each model with Yamaha. May just continue to enjoy the S950. Will wait and see.
