I just confirmed that myself. I went over to the dealer and they had 3 2016
models that did not have the multi-function switch and heater switch which a brand new 2017 did. So be careful when looking at units.
I am probably going to wait or I will order a 2017. From what I have gathered
so far the 30DS 2017's will remove the closet at the end of the counter, the kitchen sink is under the top and a covered stove top (level with the counter) to provide more counter space. I do not know if the sink has covers.
I really like the 30DS with the X-package.
