Personally, I have been disappointed since 3.But so far so good with 4. I Think it could totally happen, There have been many surprises before, I don't see why they wouldn't have something up their sleeves this time.
If the Didact is as powerful as they really say, he's definitely still alive. On a side note, its really noobish for the Diadact to have telekinesis. Its like a Sith Lord using force choke 24/7 instead of actually fighting someone with a lightsaber.
I like him, but the fact that there is no point in the game where you actually fight him, but instead go into a quicktime event for the boss fight was kind of dumb to me. Halo has never been a quicktime event game. I did like the wall jumping/climbing part though, that was fine because it was not an major part of the story.
He has to be involved in some capacity in the other two games in this trilogy. I doubt that 343 would invest in giving him the antagonistic role only for him to fall to his death after having a grenade stuck in his chest. The 'fight' would be a bit of cop out if it ended like that too.
No, I can definitely see him returning and potentially giving MC a good fight down the line.
He seems a bit too much like every bad guy ever. Darth Vader force choking while wearing Lord Sauron's armour, then he falls into a volcano like Gollum. Also during the part where you are flying through his ship I had the Star Wars theme going through my head, it all seemed pretty familiar to me. It was fun, but I'm not sure if it was original.
I think that this villain has potential , you also see another side of him in the Terminal Videos, Its cruel and ironic. I think its better than, LOOK ALIENS, LETS KILL. He has motives that actually mean more than what it appears.
I agree that it was a let down how easily he was beaten but I wasn't exactly surprised by how it was done just because that it seemed there was just no other way that master chief would have been able to do anything to the Didact.
I really wish there was more of a Boss fight for the Didact. I mean, you walk out on the Light Bridge, Didact appears from behind and forces chokes Chief, Cortana and her clones show up and tie up the Didact, and then Chief plants a Pulse Grenade in the Didact's armor.
I think he ties alot of things in the Halo Universe together for this and the lest 2 games to come, so if he doesn`t come back for the 5th game then we can probably expect to see him as the final boss in 6. Those are my thoughts, anyway.
