Samsung applied for a patent on a 28mm f1.4 with 75 deg FOV, 44 mm image diagonal lens (35mm full frame). Why would they be interested in full frame lenses is beyond me, especially when there is a very low chance for Samsung to re-enter the DSLR market. Yes, the Samsung GX DSLR line is dead (source). In the future, concentration will be on the just released NX product line. The Samsung NX10 (listed @ B&H for $699.99) will be the first in a series of future NX products (source).
On another note, CNet Asia spotted a flier at Samsung's CES booth with a drawing of a 3D camera. The design looks very similar to Fuji's 3D camera.
