I think that the Aurora LE will come out around the same time as the Diamond edition release so it will be around October, equivalent to Ariel and Cinderella. Which means that her LE preorder should be coming out around the time of the Maleficent movie release (as it is currently marked for a release in early July but who knows this could be pushed back).
Because of the release of the Maleficent movie this makes me question if Disney will release a Maleficent during the movie promotion or as a surprise release as part of the Diamond edition release. Or there is also the possibility that they will release two Maleficent dolls one based on the cartoon and the other a hybrid of the movie and cartoon character like they did with the LE Queen of hearts as it is highly unlikely that they would make one with a likeness to Angelina Jolie.
It is highly likely that we will be seeing a Frozen LE doll release at the end of the year but I doubt there will be one before the release of Ariel as the only major release coming up for Disney before then is the Lone Ranger and Monsters University and I don't see a doll being made for either of the franchises. There is a slight chance that Disney could release a LE doll on the Monsters characters like they did with Buzz and Woody for Toy Story 3 and that may be the next “couple” that the cast members have been hinting on?
So the way I see it, in my opinion what I think is concrete would be the next doll to be released will be Ariel in Oct with preorders in July, followed by the next designer equivalent line to be released at the D23 Expo in August. The surprise release for the TLM line will also come out when the Diamond edition is released in October and I am hoping this will continue to be the villain release, be it Ursula or her in her Vanessa form.
As Frozen is set for a late November release I think the LE doll will be equivalent to the Calhoun that was released last year? It was around late October early November so this may come out around mid-November before the movie comes out. Just like Calhoun did.
Then I believe that when the DVD/Blu Ray comes out (probably around mid-March – early April) they will release another doll? But who knows they may release a two pack to so that they can use both Elsa and Anna as I believe most people would love a doll of both characters.
In 2014 what is interesting is that the line of movies expected to come out of the Disney franchise has a similar pattern to the releases this year. You have the Muppets coming out around March (the equivalent of Oz this year) so we may see a Muppet LE? But then again you have Maleficent coming in July (the equivalent of the Lone Ranger this year) so they may just release a doll for Maleficent and none for the Muppet movie (so the reverse of this year where a doll was released for Oz but not for the Lone Ranger).
Then later in the year you will have the Sleeping Beauty Diamond edition release in Oct so that is when Aurora will come out as an LE with the possible surprise release of Maleficent (if she was not already released as part of the Maleficent movie).
What I find really interesting is the first Marvel/Disney movie Big Hero 6 set to be released in Nov 2014 (this will be your Wreck it Ralph/Frozen equivalent for 2014). If they follow the same pattern then they are bound to release a doll based on one of the characters. If they do I hope it will be based on Honey Lemon (I know the name sounds silly but the character would look amazing as an LE doll).

This is based on my speculation and my analysis of the historical releases in comparison to the future releases and trying to determine a pattern, but as most people have mentioned on here, Disney does seem to mix it up a bit based on the reaction of the public to the releases so it could change drastically.
But I have no doubt in my mind that we will definitely be getting an Ariel, Ursula and Frozen (not sure which character but most likely Anna) this year followed by another Frozen release early next year and an Aurora and Maleficent in 2014.
Then hopefully in 2015 onwards Disney will release dolls of those that they missed such as Pocahontas and Mulan as I cannot see how you could miss these two epic characters.
