Why I am not worried about getting FFXV on the Xbox

People honestly think Square will take time and effort to bring 4K resolution to Scorpio 1 year after game came out, with Xbox sales likely accounting for 10% of sales or less?

Remember base game runs dynamic resolution from 765p to 900p, it wouldn't run in native 4K on Scorpio, no way.
Maybe 1800p-2160p (4K) dynamic resolution but if they were going to do it then 1440p 60 Fps would be the best option.

Think you completely forgot that money talks. 

Its not hard to get a game running in 4k. Some PC indie games have 4k options.
