Agree with MrFewkes, I just can't see them wanting to disrupt the SERPS significantly in a short space of time. Significant disruptions to the usual service are surely not a positive signal to shareholders? Changes, if they are coming, would be gradually phased in.
However if there were to be significant changes in link-based ranking factor I would guess at;
Dialling down anchor text power - to me, lots of keyword focused anchor text screams 'unnatural!'
Increased trust weighting
Increased weighting on links from topic specific pages, or from links which are close to topic sensitive paragraphs, sentences etc.
