The president of Nintendo announced today that the 3DS will have tougher anti-copying measures than the existing DSi to help curb piracy.
He wouldn't say to what extent they were moving to in fear of tipping hackers off on what they need to do to exploit the gaming system but, did say it was important to step up copy protection measures.
He did add 3D may not be for everyone so it will have the option to toggle between 2D and 3D through a dedicated button.
