Unlikely since they literally just posted this now.
If there's a delay wouldn't they announce it along with it?
This one tweet feels a little risque in my opinion. They are taking one very specific side one a very divisive issue here. And of all markets, gaming seems to be among the ones who are the most actively anti-woke posturing.
I can understand the postponing. But straight up tweeting #BLM just does not look like a safe move to me.
