Ubisoft reportedly considering fresh business to own Assassin's Creed and other big franchises, co-owned by others like Tencent

I don't think they want to sell the company. I think the family that owns the majority of it is doing everything possible to stay in control of the company called Ubisoft, regardless of how many of their IPs they still have left when the dust settles.

Tencent is supposedly low-key interested in buying something. It's a rumour though so credibility is unknown.
