We have no idea. The methods used to factor number continue to slowly get 
better, and it has been quite a while since there was a single large 
improvement. That could mean that there are no more improvements to be made, or 
that some smart cryptographer who isn't focused on the SHA-3 competition is 
about to make another big improvement, or something in between.
