So, Konami was involved in the manufacturing of the gaming PCs which were done with eSports and 120Hz in mind. Speaking of 120Hz, some of Konami games will be supporting that such as Beatmania IIDX Infinitas and Heroic Verse with the latter for the Lightning Model cabinet. It seems that many other devices with 120Hz were recently announced but who knows which games will be having that besides using 60FPS as default?
Currently, it may seem that Beatmania IIDX is getting 120Hz support but that's not the only rhythm game to have it in the arcades. Bandai Namco is announcing the same thing with the new Taiko Drum Master game. I assume that it will be next-gen as the current-gen Taiko Drum Master games in the arcades are still running at 60Hz. I guess that the current Taiko Drum Master games in the arcades are still at 720p or something with the upcoming next-gen being in 1080p with 120Hz support and the QR Code Reader. The upcoming next-gen Taiko Drum Master will be released on System BNA1 which uses Windows 10 IOT.
There's even Bemani Pro-League whose inaugural year will begin in May this year starring Beatmania IIDX although I don't know if the ARESPEAR gaming PCs will be involved or not. Other games to be parts of the eSports scene are Pro-Evolution Soccer series although I don't know if the other franchises will be part of it as well.
