I personally think it will be one of the current top 4 and all of them would be great stories: MJ because it's about the only thing missing from his CV, WFP and AN for the grandslam (and AN hasn't won Badminton before) and Jock because it would be nice to see a new name on the trophy.
Hard one ,
Michael Jung and Sam I think , youbhave to admire the consistency and strength in all three phases.
If not WFP then I think PF and redesigned who I think is just lovely.
