I hope the game is as good as the previous ones. I'm very curious about the story.
I think it is possible, that like in the first two Syberias they split the new storyline in 2 games (Syberia 3 and 4).
That would be no problem for me, if each game has the length of Syberia 1 or 2.
It would be very bad if (like Dracula 4 and 5) they simply split one new game in two semi-long games.
