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.

My cynical view is different.

Garmin announced WAAS upgradeability to compete with the CNX80.

Garmin acquired UPSAT, and with it the CNX80, eliminating competition.

WAAS upgrade for the GNS series, you ask... yeah, um...


That makes no sense from their point of view. They make money by coming
up
with new things to sell you.

Assuming they make money on those $1500 upgrades...


True. I suspect that if you take out the developement costs (which they
would incur anyway), that they will make some (perhaps not much) money.

So going back a few years, did Garmin really intend to produce a
WAAS upgrade, or was it vaporware to fend off competition? And since
said competition is gone...
