The changes to the press kit weren't big ones, but...

The fact that leth is changing the press kit in the first place to be more up to date could mean something.

So the only thing that changed was changing twitter to x/twitter so the press kit was more up to date, nothing actually on silksong or it's release.

However, the fact that leth is making sure the press kit is up to date now of all times could mean that he's planning to send out the press kit soon. Meaning there will be news to report on that necessitates the press kit being sent to, well, the press. Which essentially means news soon.

I get that it kinda sounds like cope but I do think this pretty plausible, especially since we're kind of overdue for real news at this point. With that being said don't get your hopes up too much since nothing is guaranteed still.
