As I think you know, 2010 Worlds was not a carbon copy of 2010 Vancouver. Davis/White won the small gold medal for the FD at 2010 Worlds, although Virtue/Moir won the overall event.
If Virtue/Moir still have the fire in their bellies to compete in Japan -- with no guarantees of the outcome either way -- I take my hat off to them.
True. There was some movement in the dance standings. Some teams moved up and some moved down. Some retired. And it was a closer contest between V&M and D&W than in Vancouver. But in those days V&M were at their peak and were regularly beating D&W. Over the past 2 years, D&W have been on an unbroken winning streak. So although the outcome is not guaranteed, the odds are more in D&W's favour than they were last time.
