this is a question we have all been asking since the delay. When do yall think we will get more news? I personally think at least before the end of the year we will hear something. They did recently announce that they have not yet decided on an exact release date, which makes me think they are probably aiming for an early 2021 release, but may shift it to fall.
They’ve also stated that due to the release change they’ve also had to realign their press/marketing campaigns - which includes when they drop information about the game.
We’ll just have to be patient and let them do what they’ve got to do. I’d rather them spend time making the game than trying to put together another half baked gameplay demo.
There is also a dozen threads on this topic, usually worth trying to keep the conversation contained into one place instead of having the forums full of duplicate threads 
I’m not “in the know”, but I’m very familiar with business decisions. With that in mind, I suspect Infinite will be delayed until Holiday 2021. That’s a key revenue generating time frame, so I can easily imagine Microsoft telling 343 to release the game during the next holiday shopping season.
That’s all speculation of course, so I don’t want to come off like I think I’m right. It’s just an educated guess.
