Samsung has the SC-D6550 DuoCam on the market. The VM-F7500 looks pretty similar to the SC-D6550. So I am not sure if they are anyway the same and only have different model numbers for Korea. As far as I can read the translated Korean press-release (I do not know why Korean to English automatic translation is so bad compared to Japanese to English), the VM-F7500 has 5MP CCD and the Video Camera has 900x Digital Zoom. The VM-F7500 supports 16:9 video recording.
Price in Korea is 999,000 Won (~1000USD).
