I see this with mixed feelings: on the one hand, it's great when Lego really focuses again on the classic bricks. After all, that's the part that makes Lego so brilliant. But if Mindstorms has to go away because of it, I'd find that a shame. Mindstorms is simply brilliant. Ok, the other computer kits are rather mediocre, but the original RCX kit is really great.
Fortunately, I already have two RCXs and enough small parts; I can already tinker quite a bit with them.
