Now this is only a rumor so far but with Nintendo’s track record of questionable tactics and “trying too hard to be different” nature, if it’s true it really won’t be a surprise to most of us. There’s been limited confirmation as to what and what not will be used for the NX, with some sources saying it will be digital only and others saying it will support physical media.
Regardless of what has been said, there had been rumors saying that it will be supported by discs as well as cartridges. Most people are aware that cartridges are more expensive and at times have far less memory than discs have so who would want to pay more for games with less available content? We are talking about Nintendo and when dealing with them it only makes sense to them when it comes to the decisions that they make.
