(big) IF they start back to refreshing the game again, we don't normally see items offered until right before the holiday. Depending on which Tuesday the updates occur, stuff may not be offered till Oct 23rd or 30th.
I highly doubt they are putting Halloween stuff in at all. They have not put anything new in about 6 months. Last I read they were on a 3 month vacation to which I hear they maybe back now. I really wonder if this game will be continued.....township is another game maker and hasnt been fixed or updated in a long time either. This is what happened when they cancelled a few other games that were pretty popular at the time too.
