The ADS-B requirement is merely 6+  years away.  Consider that  when you 
make any avionics replacement/addition decisions.
 
1. ADS-B Out will be required where Mode-C transponders are now  required.
2. ADS-B Out can be achieved by either Extended Squitter (ES) sent  out at 
the transponder frequency (1090 MHz) or by a transceiver at 978  MHz.
3. If you fly above FL18, you must at least transmit ADS-B Out on the  1090 
MHz frequency (ES).
4. The Out signal info must have the location/speed  data derived from an 
approved WAAS GPS.
5. The ground stations will transmit weather data (FIS-B) and all  
collected position information (however collected) on the transceiver  frequency of 
978.  1090 is just too overloaded.  The  traffic data (TIS-B) is limited to 
a hockey puck shaped  space around the aircraft that is transmitting its 
position (thousands  of feet thick and 30 NM diameter ?).  Thus, if you are not 
transmitting  your own position (ES or transceiver with WAAS data), you can 
only pick up  traffic that was generated for airplanes that were 
transmitting and your  impinging traffic info may not be the complete picture if you 
are near the edge  of somebody else's puck.
6. The best transceivers will be dual frequency and receive data  from 
other aircraft (either 1090 or 978) and the ground stations (978).  
7. Transponder/navigation equipment like the Garmin 430/530 and GTx330  can 
display only limited weather and traffic info.  The FAA  doesn't care what 
is used to display received traffic/weather info. I.E. see 
http://skyvisionxtreme.com/ and  others (Dynon, etc.).
8. About 525 of the final configuration of 800 ground station transmitters  
are operational now and the rest should be operational by the end of this 
year  (or so).  Thus, all the benefits are achievable now over most of  the 
country.  See http://www.faa.gov/nextgen/flashMap/index.cfm and  click on 
BEGIN and then ADS-B. 
 
Don't cheap out!  Do your research.

PS  With onboard weather, pilots will choose the flexibility of VFR  
flights and the traffic around storms will be in more congested corridors. 
 
PPS  Checking on whether Drones, UAVs and military traffic will be  Outing 
via ADS-B.
