On paper, it's easy to negatively judge a game after seeing "xyz" has been removed. However, the real matter to consider is what was focused on instead of "xyz."
Personally, I don't want a City Folk 2.0 situation where they took the exact same game that I had (Wild World) and just sprinkled minimal improvements within it with prettier graphics. I want new, exciting changes from New Horizons. I don't need to go collecting gyroids the same exact way I've been doing it since 2001 (and getting disappointed I didn't find a fossil in that one hole), or upgrading Nooks store to Nookingtons AGAIN for the fourth time. (In fact, I'm content with Nook's Cranny being a small, pretty shop that decorates for each season.) But, my point is, I want changes to gameplay and progression more than anything else, and we can see they are pursuing that path with things like crafting and other means of unlocking content which is changing the core gameplay quite a lot.
Every review I've read has said that this game is chock full of content -- more so than ALL of the predecessors. I think we should all wait to play before we judge. We also have many patches and possibly even more DLC to look forward to.
