That’s weird, I don’t see that anywhere but to right of the picture I have:

Nintendo says preorders will no longer start on April 9th, but the console’s June 5th release date is unchanged.

I wonder if it’s because I’m in Europe?
I made a search on the page for some of the key words, and the quote you made does NOT appear for me?
And still with the quote, it doesn’t say if it’s ONLY changed for US?
