Exactly. The entire thing could be infinitely large for all we know. In any case, its size need not be related to the size of the observable universe because there is no reason why it should be anywhere near it, so it could be anything really, likely many orders of magnitude larger.
Sky & Telescope has a great, but sobering, article on this:

May have been a little media hype on this one.
