Yeah, I saw it was going to be postponed from its original release date. The Christmas Holidays are usually a period of strong box-office sales, so I'm guessing that was a good date to ensure that people are out of self-isolation, social distancing, and willing to get to the box office.
I'm kind-of bummed also. I wasn't planning to make Oshkosh this year, but that was probably the only film I was looking forward to.
