Re North Sudan is a name that is currently being used  Several other terms are also currently being used Ask any Sudanese editor about that there is insufficient basis to single out this one colloquial term above the others  Wikipedia is an online encyclopedia not an online journal  what is in use on a particular day is not determinative because it means so little and prooves nothing the longer term must be taken into account So of course it is hardly surprising that in the very month that South Sudan became independent Press Reporters writing for an audience around the world in many cases an audience that does not even know where Sudan isused the term North Sudan Press reports centred on one particular matter do not tell us whether Sudan is particularly commonly known as North Sudan  there are other reasons apparent from the above discussion including where we explained that Samoa is not Western Samoa Virginia is not East Virginia Mongolia is not Outer Mongolia Luxembourg is not South Luxembourg Ireland is not Southern IrelandYou are trying to put the cart before the horse  trying to assert as a fact that North Sudan is the common name for Sudan before time has had a chance to determine whether or not that is correct  that is CrystalBallGazing etc and  you need a consensus for your change and several editors have disagreed with your change
