When will the next all new collab be?

We know Le Sserafim will comebak this season, so we are probably gonna see a recolor or maybe a new skin, but I doubt the last.

I haven't played the game for a year now and have been only going in battle.net to buy collab skins I find cute, like the pompompurin and the panther, so I was excited for a new season for the possibility of a new collab skin.

What other collabs would you like to see in overwatch and that mercy could be a part of?

I think she would look lovely in a Fluttershy, from My Little Pony, collab
