I understand why the TF classes are broken up into DELUXE, LEADER, SUPREME etc. But what I don't get is VOYAGER. Why did they use a word which means "traveller" as a toy size classification? Having said that, SCOUT also makes about as much sense. Well, unless you see those toys as the "spies" of the line, owing to their size.
Maybe it's a subliminal message. "if you do not buy this "voyager' then it will not fufil it's destiny. Let it travel back home with your child. Set it free with your wallets".
Whatever the case, I'm just glad the size class names we've had since Cybertron seem to be the norm. When they kept changing in Armada and Energon, it got really confusing.
Personally, I think they should change the name back to "Mega." It fits the size much better by implying something bigger than a Deluxe but smaller than an Ultra.
