Update: The king is dead. Long live the king.

I'd been wondering just how close Djokovic was to taking over the top spot in the rankings at this point.

Turns out that it could happen by next Sunday if he wins the Italian Open and Nadal doesn't make the semis.

That would be a big deal as Nadal and Federer have owned the top spot since February 2, 2004 - 280 weeks, longer than any other pair of players.
