Ok, so plans have been laid out for the 4th bluewave.  It will apparently have the following features:

1. 2 new games you can play head to head using bluetooth
2. Subway maps for 24 cities
3. "Create and share UCI through SMS"
4. Custom DNSe presets
5. Voice Recording (FINALLY!!!)
6. Password protection of some sort

 I'm hoping that we can create our own subway maps for other cities.  Point 3 appears to mean that we will be able to create and share custom user interfaces through SMS (Samsung Media Studio - the software that Samsung provides, which sadly comes with DRM).
