Ok, after watching all the new trailers for Revolutions on www.thematrix.com I think I know what to expect from it.
First of all Trinity goes to the the Oracle (the actress has changed cause of the death of the first actress who plaid in the first two Matrixs, the ETM gamers allready know the new one). And she tells her that Neo needs her help. In some way Trinity jacks in finds Merovigian and (after alot of fighting having also the help of the oracle's gurdian as well as Morpheus)he helps her to wake him up (or at least sth like that I don't know how).
After that Neo also visits the Oracle. He understands that he has to defeat Smith elsewhere the Matrix will be destroyed killing all the people inside as the architect said in Matrix Reloaded. Neo then finds a machine in the real world (which might be the king of the machines or sth like that) not only to inform him that Smith cannot be controled by him (the machine) but also to cooperate with him because he (Neo) believes that he is the only one who can stop Smith, so in exchange machines won't destroy Zion.
Lastly we surely see a big fighting scene of Neo with Smith which will be in no doubt the final showdown. Neo also has the power to control or destroy machines, but it has to have his eyes shut (don't ask me why,also in his conversation with the machine he also had his eyes shut).The Matrix will surely still exist after the end of revolutions. Matrix Online will take place after it (it is an MMORPG game).
Now some dialogs and quotes...
Oracle:Everything that has a begining, has an end... I see the end coming, I see the darkness burning,I see death...
Smith: Mr Anderson, welcome back, we missed you...
Neo: It ends tonight.
Oracle(to Neo about Smith) : You are all that stand in his way. If you cannot stop him tonight then I fear that tomorow will never come...
Oracle (to Neo about Smith AGAIN) : Soon he is going to have the power to destroy this world.
Neo:What if I can't stop him...
Oracle: ...then I fear tomorrow will never come...
Smith(probably about the oracle): I am not so bad when she get to know me...
Machine (if you have seen Last res..sth from Animatrix (part 2 at the end the machine speaking and demanding...)you know how his voice sounds) : SPEAK...

Machine : And if you fail?
Neo : I won't

Bane (or better say Smith) : Mr. Andersson

Neo : It's impossible.
Bane : Not impossible, inevitable
Morpheus: Neo is doing what he believes he must do. I don't know what he can do to save us,but I know he will never give up and I can wait.
Morpheus : You never believed in the one!
Niobe : I still don't. I believe in him...
Trinity: Do you know what happened to Neo?
Oracle: He is trapped in a place between this world and the machine world
Oracle(to Morpheus) : All I can do is tell you that your friend needs your help, he needs all our help
Morpheus: As long as there is a single breath in his body...he will never give up,and I can wait...
Trinity: I know what has to be done...

Trinity(to Merovigian aiming him in his head with a gun) : Believe it...
Neo: Can Zion be saved?
Oracle : Tonight the future of both worlds will be in your hand or in his
