@NielsBoschh I would be surprised if that happened.

Google has essentially announced there will not be another toolbar pagerank update in 2013 (the last update was made in February 2013). The toolbar pagerank is the value Google shares with all of us. The real pagerank is updated very frequently, they just don’t publish that value (and as I have posted before I think they may well adjust the public value from the value they really use in calculating search results).
Matt Cutts essentially speaks for Google on this topic (though Google likes to keep things vague and unofficial). Here is a webcast where he touches on the issue a bit.
