All of the 2008 preview sites that I've been through have indications that the new x5 will sport night vision but as you mentioned you won't know for sure till the order sheet comes out. I thought some people in this forum said that the 2008's are orderable right now in the US, (not sure about Canada). I was thinking about waiting for the 2008 as well because of the possibility of having night vision (efficientdynamics and other improvments as well on the 2008) but I'm just not sure if its worth the 3 to 4 month wait.

By the way, I've heard that the 08 5series have lane change sensors (the steering vibrates when you step on the lane) do you have any experience with this? sounds like a useless gadget on paper but you never know in real life right? (Similar to HUD, people thought it was unnecessary until they experienced it)
