as far as i know last time when i check URDU was in top five most spoken languages in the world and bangali was at no 4. u need to remember in india there are more than 3000 offical languages. thus the number u put up there for hindi i srsly doubt it since urdu is also spoken in india and most of the muslims in indian do speek urdu and its is one of the major language in many states.

im not here trying to say well urdu is most spoken than hindi or start any flame abt it but im just saying how can these stats change so quickly and i do remember some1 posting it here.. where urdu was at number 5 and bangla at no 4. and hindi was below it so i dont know how correct these figures are...
