New transponder mode S vs. mode C

You need a graphic display device, like a Garmin 430 to see traffic.
Beware. The FAA has announced that new radars will not support the Traffic
Info function, so the main advantage of Mode S will be gone. I would opt
for a low cost solution, as eventually ADS-B will obsolete both Mode S and
Mode C transponders.

I read somewhere that mode S transponders were going to be the data-link
platform for ADS-B, though it wasn't clear if all mode S transponders
would be capable of it. Has the FAA chosen some other other platform?
