The Reeds have dual citizenship? I guess then they will be able to compete for Japan at the Olympics. If they continued to compete in the US, where there are many top-notch teams, they would be very unlikely to win an Olympic berth.
They will be competing at 4CC so we can see how the Reeds stack up against US and Canadian ice dance teams. Moving up to Senior from Novice is a pretty steep step. But then another US brother-and-sister team, the Hubbells, went from placing 2nd in Novices last year to becoming the JGPF Champions this past fall, so you never know.
