I'm pretty sure the official language also uses a VM like
on RCX and Spybots, so there you have your "massive overhead".
Lejos is a good approximation of a Java VM in the RCX,
and the NXT has 2 to 10 times as much memory depending on
what you can do with the flash part.
Even on the RCX speed is not a big issue, memory is the problem,
so the NXT will be a huge improvement.

C is not ideal for human programmers :-)
I'm sure there will be plenty of languages to play with on the NXT.
