My prediction, for what it's worth.
Cavendish to Sky - maybe a "train" engine or two with him - but Edvard B-H, Thomas, Swift, maybe Stannard ain't a bad train - Thomas last man? remember Brailsford keeps emphasising that the Olympics are much more important than the Tour, so building a UK train for Cav is a priority.
And - my thoughts, Wiggins to go - my punt would be for him to go back to Garmin.
