Nintendo always had a reputation of being the least open to 3rd party and indie developers. The company promised repeatedly to turn that around, and it seems like it is finally fulfilling that promise with the Nintendo Switch.
A Nintendo representative shed some light on the company's plans for 3rd party and indie support during the Game Creators Conference in Osaka, Japan. Ultimately, the process of bringing a game to the Nintendo Switch would be very similar to the one in place now for the Wii U and 3DS at the Nintendo Developer Portal, with some minor differences that are not yet detailed.
More importantly, the Nintendo representative revealed that the Switch's development kit will be priced at around 50,000 yen ($440). This is only $140 above the retail price of the regular console. For comparison, the PlayStation 4 and Wii U development kits are priced at around $2,500 apiece.
