On cswiki we deal with a similar problem. For OWE we have got a long intro when creating a non-existing page (take a look), but in NWE/VE that long text is transcluded into this small notice box (take a look).
Shouldn't this be in some form of editintro as it is in OWE?
PS: Is there a way how to make different MediaWiki:Newarticletext for OWE and VE/NWE? Is there a way how to hide the whole notice (e.g. by user script)
