Wouldn't be surprised if it gets announced next week as most UK dealers launch have a launch event next Thursday evening with test drives from next weekend. The Sport model must have accounted for something like 90% of UK X5's on the old range so it would make sense for details to be availavble from then. I believe that across the range BMW sell more Sport models as a % of total sales in the UK than anywhere else in the world, definitely the case for Europe.
