My first year was 2016, so I didnt see the last Insidious house. But, there have been two new Insidious movies since then. I personally love the franchise, so even if it is a repeat IP, there's some new material to reference since 2015 for the guests who saw the original.
I didn't go in 2019 either due to having a fresh newborn at home. So, again, another repeat IP with Ghostbusters that I didn't see the first time lol and again, there have been two movies that can be referenced for new material since that house.
I DID see the last TCM house. Its not my favorite horror franchise, but I'm sure creative will still turn out something enjoyable at the leaset. Although like OP said, this rumor came out of nowhere so I'm gonna take that one with many grains of salt.
