The new Samsung EX2/EX2F are rumored to be announced on June 26th, 2012. The cameras are expected to have f/1.4 aperture (the previous TL500/EX1 model had f/1.8 aperture).
Update: The EX2 will be using the same AMOLED screen from the NX20 model, Samsung calls it Clear AMOLED.
Also, the previously reported 55mm f/1.8 lens is really going to be a 45mm f/1.8. Samsung reduced the focal length in order to create "a real" pancake lens.
