I think we're pretty much guaranteed 10s so that the BBC can say Wembley was fabulous and congratulate themselves on a fantastic job, even though there are bound to be some of the same complaints about last time (poor camera work, dodgy sound quality, not being able to make out which dancers are on the floor by the audience that are far away etc.). On the plus side, it must be a real buzz for the contestants to be performing at wembley, and I think their enthusiasm can be infectious. I'm looking forward to seeing ott costumes and props.
