Also another interesting bit from the article, Macronix is one of the suppliers expecting orders for the new system.

Macronix makes 3DS cartridges for Nintendo. So say bye bye to discs (most likely), but this has been predicted here for a while, it's one of the few thing Rol and I agree on. 

Yeeeeeeeeeeeeeeeeeeeeeeeeeeeeees! Game Cartridges baby!

Now Im hopeing the console has 2 lines (portable & small homeconsole) that both use cartridges.
