There are two issues here. First, the NXT is slightly larger than the RCX,
and therefore requires more shipping space. Thus fewer NXTs per UPS truck, etc.
The only way around this was to make them smaller (we on the MUP/MDP pushed for
making them about the size of a 2x4 brick), but LEGO did not choose this
approach (something silly about batteries, I think).
Second, shipping time is known to be inversely proportional, in a statistical
sense, to desire. So part of the problem is that you are expecting it so much,
it's slowing the shipping. This is a well-documented physical principle ("a
watched pot never boils" etc.), and there's just no getting around physics.

wow, i'm really going to have to experiment with my power supplies some more.
I had no idea you could derive shipping information from the line
fluctuations...

This is absolutely true. (*1) I went on vacation a week ago Wednesday, and was
REALLY hoping mine would get here before I left. It didn't. But sure enough, as
soon as I had left, and didn't care about whether it came this week or next, it
showed up. Sigh.

(*1) Well, okay, that's just one data point, which doesn't make for a valid
theory, but this has happened on at least one other occasion. So I think it's
okay to generalize.
