I would be highly surprised if NI was not part of the Republic by, say, 2040. There's just many reasons why the current set up is not tenable.
Scotland at this point is 50:50. The Bats have the initiative and momentum, but a miscalculation on a second referenda could derail the project; and staying too long in power could induce fatigue.
Welsh independence is ... Unlikely.
This is a interesting point: i wonder how many right-wing inclined Scots actually sympathise with nationalism, but are currently opposed to nationalism because they would not want some "multicultural, pro-eu, SNP-led" left wing independent Scotland.
Unlike in Catalonia there is no significant right-wing scottish nationalist movement, while the unionist side is ideologically diverse. I dont think that said voting group is very big (maybe ca. 5%), but in a close referendum they could make the difference.
