I think setting up a trello would be a good way for the community to see whats upcoming as well as for preventing duplicate ideas and suggestions.
(Edited) I got bored and started to add stuff to it. Proof is in each card's description. I'll try keeping it updated as much as possible.

Thanks for organizing this. I am planning to make a roadmap soon, once things calm down a bit on my end. Not sure whether it will be Trello, on the Wiki, a Google Doc, or something else.
