Stronger GPS on the way?

Does anyone know anything about the US Chamber of Commerce's recent announcement of L2C GPS capabilities on the way? I've been searching for some extra info for a bit, and it seems that there's at least one satellite up there broadcasting on this band. Are there actually more? What's the time table? To summarize, L2C is to be the civilian version of the military's L2 frequency, which is transmitted at higher power, meaning better reception under cover, through walls, in cities, valleys, etc. There's a pretty decent summary here

Yes, there are more satellites up there capable of broadcasting the L2C signal, and future satellites being launched to replace existing satellites will have the new signal capability as well. The announcement coincided with the government finally taking the signal out of "beta" so to speak and make it available after a period of testing.

From what I can tell it will be several years before we have a full network of L2C signals and even more years before these signals are integrated into receivers available in consumer markets. There are already GPS receivers for commercial applications which will "listen" to the L2C signal but they cost several thousand dollars.
