The 46E2000 ships in July. I picked up a 50E2000 last week from my dealer. You'll notice that Cable Card has been eliminated along with the RGB PC input. These two features didn't mean nothing for me so losing them isn't an issue. I don't mine the second HDMI input though, even though my receiver does HDMI switching. Certain buttons on the remote are laid out different also, mute is now down by vloume up & down. Menu settings are slightly different, such as external inputs, which is on the top now above favorites, cable, antenna, settings. Picture quality is still great. I returned a 50A10 that was taking to long to power up along with some additional clicks that I didn't like. My dealer swapped me even for the 50E2000.
