I saw that #3 too. That sounds promising. Not only does it mean that they can add things between releases as they see fit, it also (at least potentially) means that they can keep things secret better as the answers won't necessarily be sitting in game files.
And, secrets won't be discovered in the beta phase ahead of everyone being able to look for it (whatever "it" is).
