highly doubt 16:10 will get popular anytime soon. Ever since 2008-2010 the popularity of this resolution went nose dive down. There has been some resurgence lately, but considering how common 1920x1080 is and also 4k having this resolution and most ultrawides also having 9 vertically.
Yeah that wont happen. Just look at ultrawide, definitely more popular than 16:10, but the adoption has been abysmal so much so that people with ultrawide are still considered niche. At least games start to support it more often.
