Never assume.
I just can't see Sprint keeping the preorder links live and not giving anyone a hint as to what is going on. They should be one of the first to know if there is an issue. Why ignore it? It's Tuesday. If they ignore the problem and then make an announcement on Friday saying that it is delayed a couple of weeks, that's going to be a bigger problem. I can only "assume" they aren't that stupid. It's the only way I am not freaking out about this craziness drama.
