I'm sure it's been said already but......
Comparing what modders are doing to what the company is doing is a little unfair (Some exceptions clearly apply). A modder can put out a new version of their mod every few months, or weeks even, and it can be just barely passable with some improvements each version and people will love it or applaud it, and the parts of the mod that are broken people will excuse as "well it's just a mod it won't be perfect"
If a developer takes that approach of piecemealing out content/fixes/features, and they don't work right out the gate, they get torn apart. So saying CDPR is taking too long to do what modders have already done is a little bit much. Saying CDPR should be looking at these mods and seeing if there is a way to properly implement official versions that work better into the game is fine. All devs should take a look at the modding community and find inspiration for add on content and sequel projects. Bethesda which has it's issues at least is somewhat forward thinking on this they even make Console modding possible, granted not the same way PC modding happens but still.
But back to my point, saying "There is a mod that does this and it's a little broken but at least it's there, why hasn't CDPR done it?" that's crazy. For all we know they are doing it, but all those animations and controls and features need to be perfect especially after how the game launched so If it is in the works they should not rush it at all. IF they drop a surprise 3rd person mode, and it's broken, the backlash would be insane and none of the leeway given to mods would be given to CDPR. So if it is happening, its going to happen when it's ready and not in the "coming when it's ready" from the original trailer way, but like actually ready with 98% perfect functionality.
