That is a flaw in your thinking,everything has not been reset but only adjusted as it greatly uses the same main storypaths of the original and reboots that on themselves are also remakes which is also a flaw in your logic do not do that.
But still by default this is a remake,as a reboot is a remake but it is not even the reboot you are thinking about cause you calculate some new elements in it a bit too weighty.
Come one do you think they lied with intent to consumers over something so obvious about a product that they consider one to bring people back to the franchise?
No, that's just not the case. A reboot is not necessarily a remake. A reboot restarts a franchise. A remake is a new version of a particular game. A game can be a reboot without being a remake or vice versa.
For example, Tomb Raider 2013 is a reboot. It is intended to serve as a starting point for a new version of the Tomb Raider franchise. Yet it has never been referred to as a remake, because it is not a remake. It is not using any specific Tomb Raider game as its base, it is telling a completely original story, and its gameplay/visuals/environments/settings etc. are not from any particular game. If Tomb Raider is a remake of a past game, what is it a remake of?
Not to forget that this is at least a trilogy and a company that want to stay on the market so lying and deceiving customers isn't how they would plan to make this a success.
Yeah... because developers have never misled consumers before... :-/ Inconceivable.
