Once Betfury has their licence I suspect all the top slot providers will be added and I can't wait!
When they get their license, they will have to start implementing stricter verification procedures and restrict players from certain locations. Depending on where you are from, you might not be able to play the slot games you want because your jurisdiction is not supported by the game provider.
For example, Yggdrasil, GameArt, Microgaming, and certain NetEnt games have many prohibited locations that players should familiarize themselves with.
