What do you mean, how will they keep up the hype about the game? I mean to may is a long time, for feeding us with new stuff.
Because they show us already the best new features about the game, what would they do now?
Only things we don't have see is yellow turban and the classic mode of the game.
But i think her biggest news, with dong zhuo was a lot to early now. The hype would gone to May, for the most of the customers.
They can make Lets Plays, but I think to get now 10 Lets Plays Videos every Week one, would a bit boring. And for me, I don't will see so much Lets Plays, because they destroy my interest, when I see any single step of the game.
But now we know all factions, the map, all new features(?). I think they have made all these trailers now a lot to early.
