Definitely excited about the game, but I'm quite curious how Niantic will try and keep the players in. They will need some sort of real multiplayer feature that actually has an impact on the game. They did it well with Ingress, but I felt that Pokemon Go's multiplayer side fell flat. Gyms and Raid battles (battles as a whole) really left a lot to be desired.
Will definitely give it a go when it's out though, I do hope that they wont have the same server issues that Pokemon Go originally had!
