Feel free to not buy and protest EA methodology.

Its done enough that if they stopped here, it was worth the price I paid for it. I would be upset if they did not finish it, but its that good already.

The game is probably about 50% done, so 2-3 years is my best guess. It has more content than 50%, but it lacks some polish (optimization, bugs, etc) and may have more minor updates like H&H coming (or not?). Add it all up, Bet on it being a while yet.
