This is a pool for guessing when the 500th language Wikipedia will be created, and what that language will be. This is not a serious pool. List of Wikipedias will be used to determine the winners. There will be two winners: the one who comes closest to the correct date, and the one who first predicts the correct language. The winners will be entitled to contribute mightily to the new edition. Losers are expected to contribute even more to that edition.
The current number of languages with active Wikipedia editions is 332. You can see an up to date figure on m:List of Wikipedias. The pool will close when the number exceeds 400.
Add subheadings below as necessary. You are not prevented from choosing languages that others have already chosen. You may comment on predictions so long as the comment is distinct from the prediction.
