It could have been a great quad but for injuries that undercut both of the D&S's at the end (plus Isabelle Delobel had a baby). This left Virtue and Moir in the driver's seat by default for the Olympic year. Delobel and Shoenfelder always had the most innovative programs, to me (but that is personal preference).
Delobel & Schoenfelder were also criminally underrated by judges. Even with that I think they defend their World title in 2009 without their fluke injury in the exo at the Grand Prix final making them miss that event. Although Domnina & Shabalin probably also are 2 time winners had they been able to skate at the 2008 worlds. Both teams ironically probably got their lone world title by the other being absent.
Yeah Virtue & Moir were great in 2010 but with injuries, decline, and a sequence of bad luck for both D&S teams they were in the drivers seat almost by default for Vancouver. And the USFSA foolishly putting Davis & White over the more seasoned Belbin & Agosto, when B&A would be taken more seriously by judges as a gold contender at that point, make it all the easier still.
