Barring any responses, Round 2 recently retooled the classic MPC kit. It includes a better Vader figure (I mean, how could anyone do worse than the original? Oh wait, there was the Snowspeeder crew. ) as well as a retooled hatch and wing panel end caps, and clear guns.
The original inaccurate wing panel end caps on the MPC kit were used as-is on the movie prop TIE Bomber, so I bet there will be a run for the old kit by scratchbulders now that the tooling has been altered.
