the last things we got were attractions from 2 years ago, but after that we got the option to send 2 new characters over there. based on that there might be a chance theres more to come. but in the last event they spread a pretty negative vibe (which is the same as the forums reaction to KL) which lead to homer saying please lets never go back, so it might be the end, who knows^^
