The Resetera user who has started the rumor is Mocolostrocolos. This user is no stranger to reporting, and his posts on the forum have proven to be true in the past. For instance, Mocolostrocolos leaked 100% accurate details about Metroid: Samus Returns before the game was ever mentioned by Nintendo. 

 

As with most rumors, you have to take some of this with a grain of salt. The user seems to have some inside sources and has secured Metroid info before. Is Mocolostrocolos spot-on with his latest rumor as well?
