I suspect that there are a lot of reasons including:
Certification issues
Availible engineering resources
Slow implementation of LPV approaches by FAA
There are many tens of thousands of 430s and 530 installed and upgrading
them represents a lot of revenue for Garmin, so I doubt that they are just
sitting on their hands.

Why is it taking forever?
Probably because it can.
