@Zoro:
When you see one of the spread with luffy in samurai outfit and having the kouzuki clan crest on it then I am sure it has a meaning.
Of a proved that he thought of his stories and character before they will appear years before so it's not impossible that this spread isn't a hint.
It's possible, but for this hint there are several other more recent ones that go against it.
Not to mention the mammoth one doesn't actually tell us anything except that the Straw Hats will face a mammoth, which isn't wrong. It's not like Zoro is the only one there.

@Razh:
The art of nitpicking.
I was actually going to say more things about that post.
If you are interested in me repeating more stuff, but alas, you're so bored of my posts so I tried not to mention you-know-what.
Your choice, really. I'll be honest in saying that I also don't want to keep this going.
