635d convertible Pricing with new model out ?

[phib]

Been thinking about changing mt e65 730d msport to a 635d convertible (late 2008/09)just wondered what people think will happen to the prices in the next 12 months i.e. will the value go through the floor ? now the newer car is out

Thinking about spending circa 28-30K

And views welcome

Thanks

650 and 630 have fallen through the floor and 635D is being dragged down.
