The text for "too localized" goes as such:
- This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable
Which for me is a good enough reason to close such questions, and as you'll notice, I've ended up doing so for the NXT 3.0 question, as it was very obvious in that case.
My feeling on the two other questions is slightly different, however, as I feel they are more general in nature, not really asking about what LEGO does right now but more about what they're doing. Still localized in time, but less so. Well, I contradict myself as my first comment on the train one is that it's speculative, and the answers so far indicates that the question is indeed going nowhere. Yet I can't bring myself to close it, not sure why - I'd feel more comfortable if it was closed by regular users, actually.
The question on minifig could be interesting, and seems less speculative, but again, maybe we'll be able to judge from the answers.
