Is the Petrodollar going to die out and be replaced by a stronger currency?

I’ve been reading online about certain events taking place in regard to China and Saudi Arabia. And all the sources I’ve found regarding this information seems to be from a blog or something of the sort, or less reputable sources of news.

You can read the articles in particular here:

And here

And really, if the petrodollar were to be replaced, it would mean in return super inflation here in the United States. Or just really, really bad times in general I suppose.

I realize, not many news networks, if any, are reporting anything about this… unless I’m mistaken. Buuuut, I also consider the media to be something of a method of control over the masses. And perhaps they aren’t reporting this sort of thing as to not cause panic and disorder.

Is this something I should really be concerned with, or are these blogs/new sources just crazy conspiracy theorists?
