If it has any chances of achieving that it's only short term. Long term PC version will crush it in sales, just like it was with first rebooted Tomb Raider, where PC sku sold over 4 mln copies and is still doing pretty damn well.
Perhaps PC fanboys don't remember trying to make comparisons to console sales regarding PC and their supposed huge fanbase. Yes, by any critical measure by which consoles are judged by hypocritical hermits on this board it is indeed a flop. I don't get why this is hard to understand.
Edit: In comparison TLOU remastered on PS4
The Last of Us: Remastered Sold 1.5M Units on Day One
