I noticed that the प्रशंसक base and प्रशंसक activities for अवतार the legend of Aang is still very strong despite the fact that the series ended in 2008. Is nicktoons thinking of a book 4 Air?

I watched Korra too. But it can't compare to Aang. They appeal to very different audiences!

Agreed. They have created a very different look and feel to TLOK, and do not wish to make any comparisons to the orignal series. This दिखाना will be made in 4 very short seasons (or "Books") of 12 episodes each. They've been दिया a chance to develop the characters and hopefully it will get और interesting.
