Might be real, might be fake. Not first direct coming on a 1st of month.(e.g April 1st 2013, October 1st 2014.) Sakurai recently said to wait for Mewtwo announcement or something. Pandora's Tower & Sin & Punishment have been listed here for a couple of weeks now. https://www.nintendo.co.uk/Games/Upcoming-Games/Upcoming-Games-753286.html
Could just be very well researched..... (but I hope true because Platinum + Starfox = AWESOME.)
