I think the following things are going to happen sometime in the future, just don't know if all will be in 08
1.maybe a more efficient x-drive like the new 5 series.
2. direct fuel injection for 3.0L I6 engine
3. twin turble I6 like the 335i, and 535i
4. 3.0 I6 diesel
5. power rear door
6. electronics power steeling wheel (replace the hydrolic one)
7. sport transmission (like the new 5 series)
8. maybe new color choice for X5
