I have one question?

I've seen on youtube a lot of clips from the crossfire Version: Vietnam Chinese and others ..
where there is a lot of new maps and many new weapons and items.
Why is this the same game and game controllers from other countries do not have contact
with people from our version of the crossfire should be more forward and we need to share your patches in other games I saw no such delay as here.
Does someone can explain to me why?
