The updated IIHF rankings are out (h/t to Derek at Copper and Blue). This isn't quite like the ATP rankings in tennis, which are rolling over a one-year period. IIHF rules posted after the jump.

From the IIHF website:

The IIHF World Ranking is a tool to reflect the long-term quality of the countries' national team programme. The IIHF World Ranking is based on awarding points for the final positions in the last four IIHF World Championships and in the last Olympic Ice Hockey Tournament. The 2007 IIHF World Ranking is thus based on the performance at the 2007, 2006, 2005, and the 2004 World Championship and at the 2006 Olympic Ice Hockey Tournament in Turin.

The team that wins the IIHF World Championship gold medal or the Olympic gold medal receives 1200 points. In general, there is a 20-point interval between two ranked positions (for example, 880 points for the 13th place and 860 points for the 14th place). As an exception to this principle there is a 40-point interval between gold and silver, silver and bronze, the 4th and 5th position and between the 8th and 9th position in the top division. The reason for the larger intervals for these positions is to give teams a bonus for reaching the quarter-finals, the semi-finals, the final and for winning the gold medal. (The bonus formula can be changed with any alterations to the playing format).
