Not the entire thing, but some of the provisions, sure. The personal mandate is so profoundly and plainly unconstitutional, I would imagine that an injunction would be granted on that particular provision, pending a hearing on the merits of the case.
There are plenty of other provisions in which Constitutional infirmities may exist, but they're not quite as plain as the personal mandate, IMHO.
We do have to gird ourselves as some of it might survive - the excise tax comes to mind immediately.
