It also lists the Epic 2.3, which is most likely the long-awaited update of the Samsung Epic 4G to Android 2.3 Gingerbread. The Motorola Sunfire is probably just the internal codename for the recently announced Motorola PHOTON 4G, while the Samsung Chief could be the mid-range SPH-D600, also leaked as the Samsung Conquer, with a slide-out QWERTY keyboard. We doubt it is a WiMAX version of the Samsung Galaxy S II, but hope dies last.
The two LG handsets are trickier. The LG B was the codename of the LG Optimus Black when we first heard about it, so this might as well be the Sprint version of the handset with the brightest display out there. The LG Q, on the other hand, might turn out to be the LG Slider/Gelato, which is rumored to appear in Sprint's portfolio come September. Obviously the carrier has a lot planned for its roadmap, and we'll be hearing about these pretty often.
