The Game Creators Conference was recently held in Japan, where Nintendo got to divulge some more details about the Nintendo Switch, along with some input from Capcom. There was some discussion of things like how Nintendo is focusing on having their own OS for the Switch, so that it can have plenty of resources for using gaming apps alongside your game without the console slowing down.
Most interestingly, Capcom's Masaru Ijuin talked about how they got their games to run on the console. They used the MT Framework engine, and after, which, Nintendo gave Capcom access to an emulator that could recreate the Switch's graphical output on a PC. According to the 2-person team that ported Street Fighter II to Nintendo's latest console, it's exceptionally easy to port things to the Switch, rather than it is to the 3DS or Wii U. They also mention that, "the hardware structure was very easy to understand, and had similarities to the Wii U." The Switch also had far less memory available initially, and Capcom's complaints managed to convince Nintendo to offer more memory capacity in the console.
Capcom also expressed a lot of interest in bringing the RE Engine, which is what Resident Evil 7 runs on, to the Switch as well, which could mean a potential port of Resident Evil 7, and any upcoming game that uses that engine, could very well get a Switch port in the future. The company is excited to develop more AAA games for the Switch, too.
Lastly, development kits for the Nintendo Switch will cost around 50,000 yen, which is around $450-500 US dollars after conversion.
