Wasn't expecting this news already, between this and the airdate for Doctor Who looks like Comic Con is getting all the big UK news.
Well I expected it to be announced after the series had started, and that it would be the last. But I assume if that's the case it'll be announced when the BBC make it official.
Cool, I think Merlin's been getting better every series, and I'm anxiously awaiting S4. Was there really a 5 year plan, or is that just a joke? Although I would miss it, a 5 year plan sounds good, let it go out on a high note before it becomes dragged out.
I've heard there's been a 5 year plan for a couple of years now. They're saying with the early commission it allows them to focus on the writing and do a proper long character arc.
