I for one hope she sticks with the work she's currently doing.
Why does everyone want a model who happily does softcore to make the jump into hardcore? There are plenty of great babes that already do hc so why not watch them at work and leave Sandy to do what she does best.
And if she does go hc then everyone will want her to do anal, then dp's and then gangbangs. There's just no pleasing some people
I wouldn't necessarily call what she currently does "soft core" (anal fisting, giant dildos, blowjobs, watersports); quite frankly she engages in some very hard work. I would just like to see her with a man.
The energy between a man and a woman on screen is fundamentally different, and the role-playability for a male viewer is that much greater with the appropriate "stand-in." It's the breaking of new ground, which is the excitement of every "first." Of course people want to see it, perhaps not everyone, but I'd wager it's a sizable majority.
Some will want her to escalate, some won't; she's getting older and would be best to retire before people start to talk about the "old days." I would imagine that she's holding on to her b/g scene as a nest egg; do a couple of b/g scenes, perhaps an anal, and call it a wrap. If she has saved her money and not lived to high on the hog, there is no reason that she would have to continue her career into ever more extreme escapades.
If your happy with what's she's doing, how nice for you. For those of us who want more, we wait.
