The road to final installment of the ST has been quite different from the OT and PT. Many people have argued, that TLJ feels more like the end of a trilogy than a middle act. Given the waning interest in Star Wars in general, my guess is, that TROS will end up near RO levels, which was also a December release. The fact that TROS is the conclusion to the Skywalker saga might draw in more people, but given that interest is at an all time low, I think TROS just breaking the $1B mark is not at all an unlikely scenario.
DrDre, I have to say, bravo. When this thread started everyone - including myself - thought you were crazy for predicting the movie wouldn’t surpass TLJ, let alone barely break a billion. But you stuck to your opinion, and wow, it proved true!
