Honestly, critical thinking cap on here:
Why do you want to announce your thing before the competition does?
A) you have the more "flawed" product, and want to get out ahead of the announcement.
B) you want to claim and occupy some of the marketing terms, such as "super fast load times", that you think the competition will use
C) You think your last product did rather underwhelming on a global scale and The Game Awards was the best place to announce your new one, knowing even that people who do not like your product will be watching.
D) You had planned this from the very beginning to meet criteria A, B, C or criteria not mentioned above.
You always leave room in your messaging to react to competitors, but you don't change the whole project when people are already working off its framework, except for small changes.
