uhhm,... no. According to the last estimate (that I know of) it's somewhere between 300 billion and 400 billion, or possibly greater.

They just haven't gotten around to updating the majority of the literature yet.

Well, I'd have to redo the calculations, but it's really not that huge a deal, just changes the jargon around a little - from the Hundred Thousand to the Three Hundred Thousand or whatnot..
