How did Valve manage ZERO leaks before showing the updated OLED version?

I did not see anything on any forums at all and most people thought an updated Deck is atleast 1 year away.

Just 2 days ago I was looking if someone did a DIY OLED Install and today I want to check out the Steam sales and BOOOOM we present you the new Steam Deck OLED.

Yes I feel a BIG pressure to get it.
