What is the future of the UK & Ireland?

Personally I think that the reunification of Ireland is an inevitability, as Catholics steadily grow to be the majority in N.I. it will mean that should a referendum be called, which seems ever more likely, that it would likely be in favor of reunification. Though this may cause some short term tension with the minority protestants who live in N.I. they would ultimately either settle down or return to Great Britain (after all many still regard themselves as Brits despite having been in N.I. for 4 or 5 generations. Also the vast majority of the British public don't really give a toss about N.I., it has been a source of so much pain, and many don't regard it as a 'proper' part of the UK anyway as it is not part of the island of Great Britain.

With regards to Scottish Independence, I think this too is an inevitability, and the main question to arise from the loss of Scotland (and thus the loss of the United Kingdom - as it was originally established to 'unite' the Kingdoms of Scotland & England) would be what would happen to Wales. Throughout history and arguably today it has been little more than a principality, and for the best part of 700 years it was simply a part of England. They would not be able to stand alone, and a United Kingdom of England & Wales is simply implausible(also Wales never was a Kingdom so the title wouldn't make sense). I personally see, with some resentment from the Welsh, that should Ireland be reunified, and Scotland become independent, that it would quite simply be (The Kingdom of) England - with Wales as some sort of special adminstrative region - much like what Hong Kong is to China, but on a less independent scale.

Looking vastly into the future - should Scotland, following independence, then wish to rejoin in Union with England (and Wales) I think that to prevent any future independence splits and such, the 3 countries would become one 'permanent' country, most like named Britannia, as she was known in Roman Times. Thus I see in the future that when one looks at a map, it would be surprising to see the Republic of Ireland (encompassing the whole island of Ireland) and either a Kingdom of Scotland and a Kingdom of England - or quite simply (assuming we still have a Monarchy) the Kingdom of Britannia.

Thanks - your views please.
