The permanent buildings have been there ever since 2008 when Wicked Woods: Ripper Row opened up, yet all props that are associated with the house were removed. For example, some props from Wicked Woods were salvaged while others were simply thrown away on the transition to Cursed.
Based on this knowledge I could see a new house, but keep in mind this is simply coming from a fan. I have heard rumors of that a new house is going to Festa, but I don't want to sound like I'm clowning around.
CTC was the longest running house to ever take place in Festa Field with a three year stay, so I guess now is a good time to sail away.
