Just a weekend every 5-6 weeks with 1/4 steps for candy would be great, or a week where you can get stardust or something for every multiple of 10 you get rid of potions and revives.

I wonder if there will be an update to coincide with Sun and Moon later this month or if we will get the next 100 from Johto around Christmas / New years.

Without these kinds of events the game will die, its done amazingly well considering how much niantic seem to want to kill it off.
