That's an interesting defense -- he's keeping his specifics 'secret' from everyone, including the voters, so the Democrats can't anticipate what he'll say in the debates.
Brilliant! So his weakness (not knowing anything about policy) is his strength!
Perhaps when he runs as a third-party candidate, he can call it the "Know-Nothing Party".*
But enough laughing -- seriously, that doesn't explain why he sounded like a socialist when answering a simple question: What are the top three purposes of government?
As for the idea that only Trump has a chance of being nominated -- not true unless he gets at least 1237 delegates. If he comes up even a few votes short, he's vulnerable at the convention.

You’re funny.
I take it you are neither a lawyer nor a business person.
He hasn’t been planning this for years like the other candidates.
He has a broad platform and he knows what he wants to do.
That isn’t going to change.
He will get to the policies of it when he has more information.
It’s called being goal-oriented.
