Wasn't some of the Island Sanctuary stuff given out though?

Listed below are a few of the features that Yoshi-P provided in the interview:
Player owned island which will receive regular updates
Island begins as a blank canvas
You can place buildings (wording used by translator was, "You can say like, 'Okay, what kind of building do I want to place here? What type of materials do I want to gather? Okay, maybe I want to let my minions run free.'")
Tend to your animals and crops
Expand the territory on your island
Not a competition between players
No pressured / timed content
No high level weapons / gear
This is an area to relax. Also explicitly stated that "you can call over your friends to your island and have a chat with them, you can go and visit your friend's island"
There is "a focus on the house, the garden and the furniture, but you can see this as a bit of a rank higher, there's a bit more broad things in the mix"
I mean, that pretty well gives you a decent bit of information to work with. Sounds a lot like a Harvest Moon type of place.

We're getting our own Islands. We get to expand the island.
We get animals and crops to tend to.
We get to place down buildings. Will we be able to enter them? Maybe, maybe not. It mentions furniture. Doesn't mean it's the same furniture used in the Housing we already have. We could have entirely new furniture pieces to deal with or utilize.
