Don’t put words in my mouth.
I never referred to “Ghostbusters Day” as a joke. I’ve never heard of it (as others have stated) prior to you mentioning it. Universal, to my knowledge, has never acknowledged it in the past either. The 2019 Ghostbusters house was not announced in June. And this year June 8th is a Saturday, meaning the announcement wouldn’t take place in coordination with that day regardless. These are factual counters to your claim they would announce GB in conjunction with that specific date.
I have also never said IT was coming. I did state that NoES was rumored (again, factual), but also stated when that rumor changed in April. So, I don’t see the relevance of your statement.
