Increased support? Makes sense since it was close to zero last time. Anyway it is obvious that Switch 3rd party support will peak around 2019-2020. I won't be surprised if that's when the sales start to peak around that time. It will also be the time for Nintendo's 2nd wave of big 1st party titles. So a Switch explosion during that time will definitively be possible.
Also the 76% figure for switch games doing at or above sales of other platforms just scream good news. It looks like it will be harder for devs to want to skip out of the Switch bar any big powered games.
Edit: Also who in the world is making PS3 and 360 games in 2018? That percentage should be zero! They are also developing for the Wii U as well!
