New 2 Series Coupe vs 1 Series Coupe

Hi All,

I have been reading on the internet that the 2 Series Coupe will be replacing the 1 Series Coupe.

I'm interested in purchasing the 1 Series Coupe however should I rather not wait for the 2 Series Coupe to come out?

When the 2 Series Coupe comes out will the 1 Series:

-Become a collectors item?
-Will the value of the car increase/decrease?

Thanks.
