Originally, the game was released on Playstation Vita being getting the Playstation 4 and Xbox One releases. The Switch version is the next version to happen as this is the second portable console version next to the Playstation Vita version. It will have all the songs along with the songs that are previous DLCs for the previous console releases. One bonus celebration is that the new DLC-songs will be free for Switch users. The same DLC-songs will be available in Playstation 4 and Xbox One versions. I don't know if the Playstation Vita version will have those DLCs as well.
Basically, the game originated from the arcades as Beatcraft Cyclon although the home console versions are closely based on the Playstation Vita release and even the Switch version will follow as well. It's a similar story to how DJ Max Technika Q has similar rows of notes to DJ Max Technika Tune in which you get three rows of notes on each side instead of four rows as used in DJ Max Technika series in the arcades. Maybe the size of the device is more or less an important factor and it may be same for the upcoming Switch version of Superbeat XONIC.
The release date for the Switch version in the US will be sometime late this year although there was already a delay from the intended release date which was sometime a month ago.
