In the future I have a feeling Yamaha will make more audio styles and pads available for the S950, for purchase of course, and hopefully loop pads will be part of the selection. But first they need to manufacture and sell the "T5" that will probably already have these features on board. Just a hunch.
As far as comparing prices and features between boards, one needs to look at it from all angles. To some, the S950 may not seem to be a huge upgrade from the S910 and to Yamaha's credit, the relatively comparable price between the two reflects that.
But I'm also not sure it's that big of a downgrade from the T4, and at huge price difference, may make the S950 an attractive alternative, especially for those currently not owning a S910.
