"Eliminate Aether Currents"
No thanks. They could be planned a little better, being located in actual points of interest so you have more reason to seek them out and more likely to visit them when looking for something else.

"Free Markets"
I expect we will get there eventually.

"An ingame browser"
What? Why? This seems like completely unnecessary work, and it would be a lot of work.

"Mounted combat zones"
"Airships/Submarines"
These seem incredibly unlikely and a lot of dev work to accomplish.

The rest are good suggestions though, and some are probably likely, or at least plausible.
