It seems that everybody with an US 3DS got a note from Reggie.I can't make pictures of it now, but a few details:
-Golden border in the note selection screen, just like the valentine one.
-New stationary: looks like a notebook with a red border at the right side, and a small blue line over it on top and a bigger blue line at the bottom.
-First screen: there's a picture of a mario question mark block with the mii of Reggie in front. Taken on a table or something.
Also, there's a sound saying "Hi this is Reggie from Nintendo".
No drawn text.
-Second screen: "Looking forward to sharing some news on feb 22"(with feb 22 popping out and being underlined)
-Third screen: "Meet me on feb 22 6am PT/9 am ET at"
-Fourth screen: "nintendo.com/nintendo_direct"
Also, his autograph.
All text is popped out on the fourth screen
