They were showing it in Cannes too.
Rumour is, that nobody understood what it was about.
Now I wan't to watch it even more.

There are a few trailers on the net.
You guys can watch one of them here:

It's been a long time since I saw the first movie so I don't even remember any of the other characters' names or what they looked like other than the Major and the Puppet Master. I'm gonna have to watch it again before I see this sequal.The year is 2032, three years after the events of the original ‘Ghost.’ Bateau still works for Security Police Section 9, his job all but consuming every moment of his mechanized life. He is lonely, going home only to his savagely cute little hound dog, on whom he dotes (at one point we see him holding his dog’s oversized ears up so they don’t fall in his food). He’s haunted by the mysterious fate of his former partner, Major Motoko Kusanagi, and even though he hasn’t seen her since the Puppet Master incident, he still considers her to be his guardian angel,.
Bateau’s partner is now Togusa, who he is willing to accept only because it was Maj. Motoko who first scouted him for Section 9. There have been a string of murders perpetrated, it seems, by gynoids (sort of servant cyborgs) against their masters. Everyone is struggling to understand why these gynoids, seemingly devoid of ghosts, are revolting against their masters. Bateau discovers that these gynoids are actually a new breed of robot called sexaroids (yeah, that’s right). These sexaroids, manufactured by an organization called Locus Solus, are absent of any organic material, yet appear to have ghosts that enable to them to serve their sole function of sexual pleasure.
The enigma of these murderous sexaroids (honestly, there wasn’t a better translation for this word?) forces Bateau to consider just what it is that distinguishes his organic ghost from these artificial variants. Not much, as it turns out.
