Macbook refresh ram

[crash013]

If a new Macbook is released within the coming months, do you expect it to use DDR2 ram? I bought 4GB of the stuff when I had my Macbook before the last update to it (I returned it when the latest update was released). Should I try to sell the ram or should I keep it.

It will probably use DDR2 RAM, however it won't be 667 MHz.

Will they still be compatible with new Macbooks if they use a faster kind? And would the speed difference be noticeable?
