Wow, vaderios, I never even noticed that...
Kind of cheap, come to think of it.
Regarding the ongoing subject of Vader's hologram, I agree with HotRod. It's in plain sight, clear as day, that Vader is looking upwards, almost like with the giant Emperor head-hologram. Maybe he's using the same stuff, only not bending down on one knee this time?
I've seen this other concept on youtube, and I'm sure it was mentioned here as well, how Vader appeared on a monitor instead of as a hologram.
It looked like a damn laptop more than anything else and didn't have that authentic Star Wars feel to it.

Adywan, you're right. You should definitely keep the hologram.
