There is no doubt that Note2 is an awesome phone, the screen size is really attractive. But as Android is offering lot of options to people this particular phone can not make Apple its' bitch. And as of now lot of other devices have been introduced in the market like HTC M7 and S4 is coming soon, Note2 may not get lot of more users.
Additionally people who are interested in Note devices will also tend towards Galaxy Grand, its price is nearly half to that of Note and offers Jelly Beans with 5" screen. Sure it is not having performance like Note2 but still does the work for lot of users.
