Mid air Mandarin

An AA flight from London to Chicago had instructions inside the toilet/lavatory/rest room in English and Mandarin (or may be Kanji (?)/Japanese).

I wonder how long it will be before we see one in Hindi.

I remember having a discussion about an year ago, with some friends, about how long it will be before we see exchange rates for Indian Rupee being displayed in the big digital display outside the currency exchange bureaus at airports and other touristy destinations. I don't know the conclusion of the discussion but my guess is 3 years.
