There are a lot of people who think that Murtagh and Thorn will change their names by rescuing the last green dragon egg and that this egg will be the mate of saphira.
I honestly think that either Roran or Arya will be the new dragon rider. Roran b/c he is related to Eragon and Murtagh and also b/c the wound he got from the Raz'ak healed really quick which suggests that he could be a descendant from the Grey Folk (which these people are said to play a big part the the 4th book).
Arya is a prospective Rider b/c Oromis said in the 2nd book that half of the dragon riders were female and theres already 3 Male Humans as dragon Riders. And if Arya became the new dragon rider then that could make it so that Eragon and Arya finally are together.
I think that Arya and Eragon will be together b/c in the third book before Eragon battles murtagh for the 2nd time she says she doesnt want to see Eragon broken by Murtagh and she starts to say something else, then stops herself. And i dont think Eragon will fall in love with Nasuada b/c in the 1st book, there seems to be an attraction between murtagh and nasuada.
Also people are saying that the name "Galbatorix has almost found" (when Eragon is talking to the Razac) is the true name for the ancient language. In the 1st book, Brom says that anyone who finds the true name would have power over everyone who uses it.
Tenga will also play a big part in the 4th book, as its possible that he could also be one of the supposedly extinct Grey Folk b/c he was able to use magic without using the ancient language. Also the question Tenga is seeking could be a way to harvest energy from fire and water as Oromis says that if anyone could find a way to do this, Galbatorix could be killled in an instant.
Right now its said that the 4th book will come out in January of 2010.
Different names that people are contemplating are Empire (which was the original name of the 3rd book before it was split), Bromsson (b/c it suggests an inheritance and b/c the 1st two books started with E and the last two could start with B), Emerald (b/c of the last green dragon egg), Eldunari (b/c of the role the eldunari will likely play in the last book as it could be the downfall of Galbatorix), and also Shurtugal (b/c it also hints at inheritance and Eragon's inheritance of the Riders legacy)
It is likely that Nasuada and Murtagh could become the new king and queen of Alagaseia.
Also just because the prophecy from Angela says Eragon will leave Alagaseia forever doesn't mean that he actually leaves the land. It could mean that Alagaseia is renamed or something, but this is unlikely b/c of Eragon's dream in the 1st book.
Obviously, Sloan will play a big part in this book as will Solembum's advice from the first book. He says to Eragon to go to the rock of Kuthian and speak his name to open the vault of souls when his power is insufficient. It is contemplated that Eragon will have to speak his true name to open this vault of souls and that when he does, he will find some more eldunari from dragons which were put there in the Fall to protect them, or it could be spirits like the ones from the 3rd book, and it could also be possible that Eragon will be able to bring back someone to help him like Brom, Oromis, Eragon I, etc. but this is unlikely.
It is unsure what the Rock of Kuthian is. It could be Brom's ring, or it could be somewhere on the Vroengard. Also before Brom dies in the 1st book, he gives Eragon a spell that in his hour of greatest need he should use this. Eragon has yet to use this spell, so it is possible that this will come into play in the last book.
I think that the rock might be where the dragons kept their eldunari before the the elves came, it is possible that eragon will find this and convince those eldunari to help him kill Galbatorix. If the rock was where the dragons kept their eggs before the elves then there would be much more there than galbatorix has ever dreamed of, also it would be very challenging for eragon snd saphira to to convince the dragons, so if this was in the book it would surely be a big part of the book.
I will bet that either Roran, Katrina, or their child will be killed by Brigit, most likely Katrina will die because it was Roran's fault that Brigit's husband died, so she will take away Roran's love, and then Brigit will be hanged, and Roran will go mad with grief, and strike out against Eragon because it was actually his fault in the first place because he brought the stone home.
Probably on the offical site for the inheritance cycle.
He has confirmed that the name is Inheritance.
Inheritance cycle
green

The full first chapter of book 4 in the inheritance cycle has not been released yet. However, you can get a sneak preview at Shurtugal. com or inklet.blogspot.com
In march or may 2011
no
Book 4 of the Inheritance Cycle has no official release date yet. Paolini stated that he came up with about 100 pages while writing Brisingr, so that might speed the process up a bit. Personally, I'm hoping it comes out in September of 2010 or sooner. I read the book and listened to it on tape and he said it will probably come out in 2009
BIGGER than the universe... if christopher paolini does a good job, that is
The Green dragon will most likely be Saphiras mate
