(prediction) Mainline Pokemon for Switch will release no sooner than fall/holiday 2019

I agree, but 2018 can be a slight possibility. However 2019 is more likely because DS (2005) got a pokemon 2 years after it launched (2007), same with 3DS (2011 to 2013). But heres hoping its and open-world Pokemon game that lets you travel all the regions, and is main series.
