Yep. I wanted to copy that tweet with the datamine info but my Phone didnt let me. That's why I only comment about the Splatoon 2 update, not the direct but makes sense the two are connected
Here is the link to that tweet.

Its just well that is a long time to delay, and LOTS of leaks or surprise announcments could be released. Like WB already released a trailer for Lego Harry potter switch, which I assume would have been announced today.
Delaying the direct a full week could really mess up a lot of plans. I understand worried about being sensitive, but they also need to look out for the company.
However that information about maybe a certain game having insensitive parts could tie back, It doesn't sound like its smash though.

I think still at most the delay we get is a few days at most.
