Most likely something like this:

I don't know of any other "wood" structural system in use today that can allow buildings heights of 10-11 stories.
At least one of these have already been built in London. Obviously, building codes have to be changed or exceptions created for the building to go ahead, but the construction technique will likely become widespread in the near future.
For those of you who aren't in the know, a CLT panel is like a piece of plywood, except composed of dimensional lumber. They can be as much as 2 feet thick, and up to 40 feet long. So you could build a building using 10' x 10'/20'/30' x 1' panels, then lay a subflooring of the same stuff. CLT's have incredible strength and are more resistant to fire than any other type of building. Knowing Portland, they would probably require additional fireproofing tho.
