Quite understandable (and understood).

I wish they would, too -- I'd love to see it!

Agreed. For structural work -- especially, the sort of tinkery
rapid-prototyping structural work we all love -- LEGO can't be beaten.

It's the extensibility part that's sticking in my craw. Yes, structurally, LEGO
is very extensible. But that makes a mechanized gadget, not a robot -- a robot
requires sensors and effectors. And the RCX limits you to three of each.
That's not very extensible.
Now, if you took something like the OOPic (or similar) controller, and the cheap
and plentiful sensors and effectors that the MarkIII folks have, and used them
to control a LEGO-built robot, it seems to me that you would have the best of
both worlds.
As it is, I'm reluctant to sink $100 or more into a Mindstorms set when I could
spend the same money on a PIC-based platform, and not hit any I/O limits for a
very long time (if ever).
So why am I posting this? Two reasons: one, I have some hope that LEGO is
listening and will consider beefing up the next-generation RCX; and two, I'd
like to hear about other LEGO robotics projects using PIC controllers. Though I
suppose that should be a different thread!
Best,
