This will link you to an article that describe LAAS as being
delayed for
quite a while. Don't hold your breath.

The principle problem with LAAS is that the government has a schedule
to replace
ALL of the GPS sats with higher precision versions. I.e., the
precision of GPS
is going up, without any particular new infrastructure going into
place on
the ground or in the air.
Actually, a principle problem with LAAS is that the funding was
seriously scaled back.
The CAT I portion of the program was still in the R&D phase, as they
were working the issues (problems with interference/iono, i believe,
were still not resolved).
Which means that by the time any LAAS program got
on its feet, standard GPS, and presumably WAAS, might well offer the
same
capability.

I'd be sufficiently impressed if WAAS could provide CAT III, even with
dual-frequency, denser network of ground reference stations, algorithm
tweakage etc.
