My thoughts are that you'll be disappointed if you believe the core gameplay will be changed because people grow tired of the game when they've done it all. You're misguided in your beliefs that this has anything to do with potential laziness of the devs.

To me it seems IGS may have increased their ambition for the game, which could lead to more content, variety and longevity, but I don't believe the core gameplay will change.

For the discussions sake, it would be interesting if you could specify what aspects of - farming ore, user interface, world generation you'd like to see changes for. I wouldn't mind them improving any aspects of the game, but we might differ on what we see as improvements.
