Personally I was a day one BOTW buyer, loved it and played more than 200 hours, but somehow never had any interest in TOTK. From the reveal it never spoke to me, maybe as you say because it looked too similar. I had the same back on the N64 with OOT and MM though, played the first one to death and when the second came around was not interested. Not doubting TOTK is a great game, just not feeling like buying/trying it. Maybe there are a couple of millions like me.
