Will Motorola Mileston get froyo update?

Hi,
As far as I can tell….Droid and milestone is almost identical except some minor features.
but when it comes to froyo update…it looks like there are big difference between them
I have seen few youtube videos of people using froyo on Droid
but not a single video of milestone user using froyo yet
froyo update is very important as it improves the performance of the phone!!! and milestone really needs one
Without froyo update….milestone is not that attractive..:(
Do you guys know what is going on and why milestone won’t get an update (or device cannot handle the update???)
share your knowledge please
THANKS
