I am going to keep my post short and simple.
Will Scotland ever be free? Yes, Scotland could be free one day.
When? No-one knows. In my opinion, I think we could see a new referendum no later than 2020.
If Scotland gets Devolution Max, would that preserve and solidify the Union? In my opinion, no, it would still lead to independence.
Will Scotland actually get Devolution Max? No, they won't. Why would Westminster risk giving Scotland more powers which could have a negative impact on the rest of the UK? If we get "Devolution Anything", it will probably be the crappy Labour proposition of "Devolution Miniscule".
If Scotland did win the referendum, would they be denied from the EU? Probably not, I don't think the EU would be that stupid. Scotland is a small country, but it is a small and smart country with vast energy potential. Our exports are quite decent too. Then there is defence, it wouldn't be wise to give away vast swathes of the North Sea. You can't strip European citizenship off Scottish citizens, as we are already European citizens. Why would Brussels decrease their territory and market potential, making Scotland reapply for membership, costing billions of Euros, tons of useless paperwork and countless years of limbo, just to reaccept Scotland into the EU? That would be bonkers. If there was a technicality, then I am sure Scotland would be fast-tracked into the EU as soon as they could possibly can. There are contingency plans for these type of things, especially now.
Conclusion: Scotland would most likely be an independent country within 20 years.
Whilst I am indeed almost as English as they come, I do have Scottish relatives, I've lived in Wales for a couple of years and I consider myself British.
You're probably more Scottish than I am! I wasn't even born here. I was born in Somerset, England. I'm Scottish/Irish/English, and I am super proud of that. However, I don't consider myself British, and that is for political reasons. That doesn't make me a nationalist, as we all have identities. I will still wear my poppy with pride as Remembrance Day nears.
Edit: You know what; you can add my Welsh identity in there despite the fact that I have no Welsh connections, as I know of, whatsoever.
