Well, as long as you are not out any money, I wouldn't really be worried about it.
Just buy it in a couple days. Or get a physical copy? I don't really know. Having just checked mine, there has been no cancellation. That is really strange.
Letting history be the judge, seems like every big game that comes out has trouble with the internet infrastructure and there are lots of issues/bugs that slow down the release of the games, right?
It sucks. Nothing else to say. I don't work for EA or in the industry but I am not surprised by all the trouble. Just disappointed. As are you.
