''When thinking about it all, Great Britain or any place in our world can't be the Promised Land that Merlin was destined to build together with Arthur. ''

It's very clear that Merlin is still waiting for the golden age to begin, given that he's hanging around the lake waiting for Arthur to return. Look at the grim expression on Merlin's face at the end of the finale. He certainly doesn't look like a man who achieved his goals and is happy with the way things have turned out.

I'd say that the most likely scenario is that the kingdom of Camelot, as we knew it, fell within a generation, two tops.

Given that she and Arthur were married for more than four years without any hint of a pregnancy, it's highly unlikely that Guinevere was pregnant with Arthur's child so, even if she was accepted as Queen as Arthur's widow, it's all but guaranteed that she could leave no heir who would be accepted. A child of a second marriage or an adopted child would have no link to the Pendragon family, so I'd say that it's more likely that the kingdom would have ended up divided after her death, if not before, as it was before Uther united it.
