If you waiting for the tech that is in a Touring but want cloth seats you might as well buy now because I would doubt that will ever happen. Subaru saves their better options for the high trims.
I don't foresee that you will ever get the clot option without sunroof and get the top level features. I am sure that these will continue to be grouped together.
I however do get the feeling (I have not inside line, just guessing and gut feel) that if production issues and some of the little challenges and software glitches/complaints get worked out, they may offer some different configuration options for the 2020 model. This is a NEW car in one of, if not the most popular automotive segment. In addition, this came out earlier than any other 2019 in their line up, really giving it nearly a year and a half. If things don't smooth out, they may hold to the same configuration list.
Personally, I am with you. I am about 95% sure that the Ascent will be my next car. I am just hoping that some new configuration may come out that I would prefer. I am also hoping that if the Hype and demand drops some, I can score up a better deal than our dealership is currently offering. Keep in mind that a new model year will most likely increase 3-5% and that is if the tariffs are not imposed.
I think right now, the option is to wait to see if you can get what you want, or closer to, in a year when the 2020s roll out or possibly save a little money and get a 2019. For me, I am going to wait, I would rather spend more and get what I want then settle and most likely trade and take a bigger hit then holding onto the car longer since it is what I want.
