No. There are not 4 regions. Any changes to the Wiki should be treated as vandalism of the Wiki and prosecuted to the full extent of the law.
It is quite correct that pending our decision about the constitutionality of the original 'act' - which is claimed to have decommissioned the Pacific), there is no reason to assume that there are in any legal sense four regions.
However, in 'fact' given the 'actions on the ground' (the aforementioned 'final constitution' and the vote for intervention by the IDS legislature) is that the South is occupying what was, and may still be the Pacific.
So, there may be 4 or 5 regions - that depends on us. But the fact of the occupation is undeniable, at least by my understanding of how Atlasian reality works.
But occupation does not mean that there are now 4 regions.
