From my perspective, this is complicated because, for me, there are two answers depending upon whether I'm looking at things from the developer's or player's standpoint.
For the player, having new content added seemingly forever is just fantastic if you are really into the game. On the other hand, if the sequel falls into the "too high expectations" category and only gets middle-of-the road reviews, then players will adopt the game more slowly if the 1st game is still getting regular updates.
A couple of games that are examples of this are House Flipper 2 and Civilization 7. In fact, I'm wondering if a majority of the player base will ever adopt House Flipper 2. I can't really say about Civ 7, but House Flipper 2 is a fine game, and it's lagging way behind because they keep releasing new content for the first game.
