Future events such as Bilgewater?

What can we expect to see from Riot regarding more errr... how should i say... Nation events? Looking over the extensive immersion the Burning Tides event provided both musical and lore wise just makes me crave so much more now. I certainly hope they dont stop with burning tides and Bilgewater. The other 9 main nations/locations (give or take) could yield such engrossing immersion as well. Perhaps shed some light on the void? (pun intended???) A piltover saga revolving around Jinx and Vi & Cait maybe revealing this mysterious sister in reference by her? Given the many factions and places yet to be explored in such depth as burning tides displayed, the possibilities go on for the other main locations.

I'm just really anticipating another immersive event! http://ddragon.leagueoflegends.com/cdn/4.11.3/img/passive/Jinx_Passive.png
