The funny part about this whole situation is that whenever a Darth Vader saber gets reviewed, nearly everyone cites THE SOUND as being the best thing about it. I've heard one in person, and it is indeed spine tingling. I absolutely understand the frustration on having the same sound re-hashed, it truly is less accurate than it could (and probably should) be. But I think we can all at least take comfort in the fact that:
A) From what it looks like this new saber is a considerable upgrade in almost every other respect.
B) The sound may change quite dramatically when doubled and run through a coupler.
C) Even if it's an inaccurate sound, it's still a pretty dang COOL one to hear.
Like many here I will probably wait and read the reviews, see if it's worth my money. But Darth Maul's saber has always been my favorite, and I think it's going to be very hard to restrain myself when I actually lay hands on one. As if that's a bad thing ;D
