Because I think I'm one of them and I get the sense there are others. I've test driven the MS twice now, love it, want it, and am so close to ordering. However I can't help but think that with the model 3 release coming up soon, they're going to have to (my opinion here) announce something about the model S as well. I'm not saying anything drastic but maybe at least some interior upgrades or changes. I've read where some current new owners are recommending to hold back and take a wait-and-see approach with the MS launch. I'd be interested to see how many of us are sitting on the fence before we consider buying.
