I predict that Kerr/Kerr will win, more than edging out O'Connor/O'Dougherty, although the actual quality will be closer than the results, with the stronger of the Towler-Greene couples in 3rd by a split decision, and Humphreys/Baranov in 4th.
It is possible that the Kerrs will break top ten and earn a second spot for British Dance in 2007, but they may have to wait until 2008. If Navka/Kostomarov win the Olympics in 2006 and don't skate Worlds, and Denkova/Staviyski win Worlds in 2006, I think D/S will retire then. Who else retires I think will be based on the results over the next two years: if Grushina/Goncharov hold steady (or switch one place). I would expect them to stay in for 2007 and try for the title. If Dubreuil/Lauzon and/or Chait/Sakhnovski do not move up under CoP in the next two seasons, then I would expect them to retire in 2006; if they move up under CoP, I would expect them to stay in through 2007 for a try for the podium.
I think Wing/Lowe will not make the Canadian Worlds team, but there are several Canadian teams in the wings that could be strong competition for the Kerrs by 2007. Also, while Domnina/Shabalin might be top five by 2007, the Russian team would need an eighth-place or better finish to retain two spots. I'm not sure which team is being groomed as the third couple, but the judges' relative indifference to Kulikova/Novikov might melt away as soon as Navka/Kostomarov retire, and the Kerrs might have a challenge to hop over them.
