Krafton seems to be looking for ways to distance themselves from the PUBG creator further as they are now dropping that part of the name for the mobile spin-off.
Brendan "PlayerUnknown" Greene is the brain behind the whole battle royale mod in Arma III that eventually rose to become what we know as PlayerUnknown's Battlegrounds, or PUBG , today. However, Greene has parted ways with Krafton since and this is probably the reason why the company is looking to separate his brand from the game as much as possible.
This first led to PUBG being renamed to "PUBG: Battlegrounds", possibly as a preparation to change the name even more in the future but that remains to be seen.
The mobile version that had some changes added to it, PUBG: New State, is moving things faster though. It has recently undergone a name change, completely dropping "PUBG" from the title, which now reads "New State: Mobile".
A Krafton spokesperson noted that this is an effort to focus on making the game the ultimate mobile experience in an exchange with DotEsports . It appears the game was always meant to have mobile platforms first in mind and the statement hints that no changes are expected for PUBG on PC.
The game did receive a major change recently as it went free to play but the last time its name was changed was in August 2021, when players immediately started noting that "PlayerUnknown's Battlegrounds: Battlegrounds" sounds extremely silly.
Interestingly enough, the F2P gameplay trailer above only has "PUBG" in its title.
