Roid is a "non-console" from developer Level 5, but rather, a web portal used by the dev to sell PC and mobile games. The new issue of Famitsu hints at what to expect.
According to the article, "A surprise, big title is also slated to appear." Below that is a picture of classic Japanese role-playing-game Mother, better known as Earthbound in the West.
Next to the picture is a capture stating that new titles are scheduled for ROID — like perhaps that RPG.
Mother first went on sale in 1989, and was created by Shigesato Itoi, who's a famed copywriter and TV personality in Japan. He also voiced Mei's father in anime My Neighbor Totoro.
In 2006, Mother 3 was released in Japan, but hasn't gotten an official English localization.
