Garmin backing away from additional GDL-69 features for 430/530 products?

Take a look please at the bottom of:

According to this, the WAAS upgrade for the 430/530 will no longer include
as a side effect access to the "additional" features of the GD-69.

My understanding, from speaking with a Garmin rep months ago, was that the
430/530 products need to have a hardware upgrade so as to exploit features
of the GDL-69 that were not available in the GDL-49. You can see what
these features are at:

http://www.garmin.com/products/gdl69/

The list of features available for 430/530 users is much shorter than that
list for MX20 and G1000 users.

[And no mention of the 480, which I find interesting.]

Does anyone know of Garmin backing away from the WAAS upgrade also adding
the ability to better use the GDL-69?
