Matt Cutts (on his blog) said that they wanted paid links to be reported so that they could test new methods of detecting them.

This implies that we can expect new detection algorithms in the not too distant future.

If they can detect paid links reliably, it will have a big effect. I see paid links on a LOT of sites.
