Thoughts on new Gym rework - Raids?

So if you keep up with the PoGo news there's been a few leaks about the next update. Go check out Trainer Tips on YouTube for a few bits of leaked code and speculations about how it will work.

Sounds like the game will alert you when the app is closed about potential gym "raids" near you so you can open it up and join. Like how Ingress currently works. Also new Pokemon interactions.

This has been a public service announcement.
