I don't think the International Dateline changes what day of the week it is on a certain date of the year. In 2019, Feb 10th is always going to be a Sunday wherever you are.
Not quite true, but it becomes Monday Feb 11 in Tokyo while it's still Sunday Feb 10 where I am, here on the U.S. West Coast. It becomes Mon Feb 11 seventeen hours earlier in Tokyo than it does here. It just takes us a while to "catch up."
But the question, then, becomes "Sunday where?" If the announcement was for the U.S., Tokyo gets to Monday before we do. The sense of the statement of release depends on where you are.
This is large-scale nit-picking.

A more significant question is, will the GR III be released in February at all, or, say in July? Or better, in January!!
