ok well we know the most likely place is Gambino's Mansion in Isle de Gambino cause Gino has just returned there and he wil probably host the event.
There is also the highly likely chance that Labtech X will return and what he has instore i have no idea.
There was the wierd package that LabTechX delivered to the Von Helson Twins on easter that was never revealed but it seems that the Twins are dead now so who knows if the admins have forgotten it.
The Admins said at a convention that Grunny will return this Halloween though we will see if that information will prove to be false.
there was some odd things said in the last plot update about who different girls were going out with but i dont really care about that unless it has an affect on the halloween story.
Sasha and Ian may play a bigger part in halloween this year considering that Sasha is close to Gino and Ian is close to Sasha.
Well lets look at who will most likely be there. I think they need to update Gino's avy.
and last but not least 
If anyone has any info that i left out then post it as a comment or PM me.. thankyou.
Thanx Starry ^_^
