The translation work was highlighted by a foreign language overseer in a very recent talk to an English speaking congregation in the Mediterranean.
He said that it is currently around 600 languages and they want 1000 by September. This will never happen in the timeframe but I think there is something in the multi-lingual side of things. I think they (a) may relate it to bible prophecy and use it as a way to get out of 1 billion people not having any meaningful access to the D2D/cart preaching work, (b) want ever bigger numbers to compare to wikipedia and google language numbers and (c) try and reach more peoiple via the website
