I'm not sure, but I remember someone explaining in another thread that the cartridges would most likely be read-only...

That would make sense for piracy protection but I'm pretty certain they can be read/write if Nintendo chooses.

Surely, but that would also cost more, no?

(and could be weak against piracy, yes)
