At what point in the trailer do the flashes of red sky occur (I've watched it a couple of times, but couldn't find it - I'm probably blind :p )?

But I don't know ; the Battle of Camlann would mean the end of the series, as it is almost certain they're going to follow the legend and make Arthur fall in the Battle of Camlann. But seeing the series' great success, I personally reckon they're going to prolong it.
