I'm sure this theory will be found to hold water soon enough, when someone does a June 2009 MacBook Pro Teardown, but: Do you think that there is a 3G antenna running down to the SD Card Slot? I'm thinking that this will be Apple's way of having a SD 3G addon card down the line, even if carrier details weren't worked out just yet. In fact, I think that is the main purpose of this slot, but they won't announce it until carrier details are announced with the release of Snow Leopard and its built-in 3G networking software. It means 3G-ready for all laptops made from now on, much like laptops were Airport-ready starting with the G3s. Discuss.
