Well it technically is a wasteland where you explore and try to survive the current climate of it. Weapons/armor not breaking is pretty unrealistic. I see the point of weapons breaking too quickly but by getting rid of that you just make it easier to go through the world with one/two weapons instead of an inventory of weapons. Personally I like what New Vegas did introducing repair kits however I also liked what Fallout 3 by making repair very important towards damage, while that did hurt armor it also rewarded you for putting points into the skill.
I'm still going to enjoy Fallout 4, 82 more days, it will take forever. If it is true that weapon/armor degradation is gone, which we don't 100% know yet, then it would be disappointing. It wouldn't be the worst thing ever but it would be a disappointment because it has worked in the previous games and I see no reason why it can't in Fallout 4.
