I think if they genuinely indicate they mean to evolve the match
I received the New Horizons Items in May, I have built up about 230hrs onto it and I am still enjoying it. I really don't play every day like I did when I first got it, but most days of the week I will open it up and get a few things done.
I haven't got a set idea of what I wish to achieve with it, but as I run around occasionally I'll pick up an item which inspires a fresh idea...
