Update: This phone is now official, and called the Epic 4G.
There are reports that Samsung is working on a new WiMAX phone, the Galaxy-S Pro. The "original" Galaxy-S has a Super-AMOLED display, so we can assume that this one has the same display.

The combination of Super AMOLED (hopefully) and a slideout keyboard is a real winner in my books. Could well be my next phone.
