This episode will screw with you. I suppose it's not totally unreasonable to expect that Uther will eventually die, as he eventually dies in all Arthurian legend, because people die. It's fairly surprising that in an episode with so much campy "old Merlin", it would end with Arthur being crowned king.

But there you go, I just spoilered this entire season / series / episode / life for you if you haven't seen the show. If you do want to start watching, it plays in the U.S. on Friday nights at 10pm on SyFy.
