A post on GamesPlanet reveals that sales of Tom Clancy's The Division 2 will be restricted to Uplay and the Epic Games Store following the game's launch next week (thanks MP1ST). They reassure their customers that existing orders will be fulfilled, but that after March 15th, they and other third-party stores will no longer be distributing the game:

Hey Community!

Sadly we have to announce you that Ubisoft will not allow digital third party stores, such as Gamesplanet, to sell Division 2 after its release on March 15th 2019. After this date, the game will digitally only be available through Ubisoft's Store and another exclusive digital store. This will also be true for all upcoming game content such as Season Pass, Extensions, etc.

Take the opportunity to buy at Gamesplanet until March 15th 2019 and make use of the paysafecard promotion as this will be available until the game will be pulled from our stores.

We won't be able to solve some support requests (e.g. key activated on the wrong Ubisoft account) after March 15th, as we won't have any more keys to exchange/swap. Please address your support requests to Ubisoft directly for such cases.

Worry not, all purchases that have been completed on Gamesplanet will be honoured. This is also true for gifts, no matter if these have been picked up or not.

Obviously, we are not happy about this decision.

The Gamesplanet Team
