Wow, some of them are really great. I especially liked those involving the dragons and Kilgarrah's sacrifice. However, I don't think that it has to do with Aithusa not being able to mate Aithusa- he was glad about the dragon future even after he learnt Aithusa's name and gender. About the Sidhes, I really don't want to see more of them, except if it has to do with Morgana becoming a priestess of Avalon, like the legend, or something like that. I like the idea of the phoenix and Tristan becoming a knight. About love interests, I think that Percival looked like he had one in "the sword in the stone" before Morgana's attack.

Now, I would like to add some speculations/predictions myself: First of all, I would like to see more stories of the legend, told in the unique "Merlin" way. Some of them are:

1)The appearance of Accolon, the man that tries to kill Arthur for Morgana and who is also her lover. This role would fit Alvarr well. He could impersonate "Sir Accolon" by magic (Morgana is supposed to be a shapeshifter originally so that can happen) and try to kill Arthur. Of course, he fails and gets killed for treachery.

2) Morgana stealing Excalibur from Arthur. It would also fit well with the plot, since Excalibur has been the reason that Morgana was overthrown from Camelot twice.

3) Merlin trapped in the Crystal Cave, maybe in a two-parter. Morgana could transform to Freya and guide him there, where she traps him using magic. Then Arthur, the dragon, maybe Gwen and the other knights would have to find him and save him, maybe by confronting Morgana and Mordred. I would really love to see something like that happening, and somehow I think it will.

4) Some serious magical battles, especially if Mordred and Alvarr return as well.

5) Morgana becoming a shapeshifter. This would add a lot of plotlines to the show, as those presented above.

6) Arthur losing the trust of his people due to magic. Then Gwen would try to convince the people about him being a good king and this would also show how a good queen she is.

7) More tolerance on magic in Camelot.

8) A smooth transition from evil to good once again for Morgana, as Dryuuu also suggested.

9)Mordred becoming a great threat.

10)Morgana becoming Lady of Avalon and Merlin becoming leader of the Druids.

11) The "Merlin Will Return" etiquette at 5x13.
