If the delay is because last demo feedback we will not see it or anything new for a while.
I suspect E3 2020 will be where new marketing campaign will start.
Btw this is good example why you should never preorder anything so early - people that did this in last E3 because of Keanu CGI hype will be waiting 14 months.
All of my merch/game preorders except GOG haven't even billed me yet, and won't until the release date comes, so I lost nothing by pre-ordering early.
You're probably right about E3, but another 5 months without information is going to be hard for people to stomach.
