Nintendo chose not to launch Wii U/3DS in China but they did launch in Asia where the consoles didn't do well. Main reason is lack of localisation support. Only very big games get localised but smaller games are in Japanese..... for a Chinese audience.....
For NX to succeed it needs the no region lock, it needs localisation, it needs social online features in games at all times + cheap pricing in line with other consoles in China.
So do you think there's space for a Handheld market for at least the followup to the 3DS ? Plus are Steam machines a thing or what ?
