Less reliance on magic items does not mean that PCs will have less magic items by default. It means the magic items won't impact the power of PCs as much as it does now, so that we don't need to follow wealth by level guidelines. So, if you don't want to cut back items in your own campaign, you won't have to re-balance the encounters.
Yeah, the entire idea of "less reliance" on magic items implies there is still reliance on magic items to some extent.
I still have a feeling that you'll need to follow wealth by level guidelines. They will just be less important than they were before. So, if one player has a +2 sword and another one only has a +1, the difference isn't that big since it's only a 5% chance to hit and one extra damage. On the other hand, in 3.5 you often got into a situation where on character had a nonmagical weapon and no stat enhancers and another had a +5 flaming, shock, keen, frost weapon and a +6 belt of giant strength. This made one character way better at combat than another one.
I think what you'll see is that the expected amount of magic items will decrease dramatically but it'll still be there.
In 3.5 it is expected that you can get a +10 equivalent weapon by the time you were about 18th level.
If you change this to expecting a +6 weapon by the time you are 30 and spread this out across all levels, then you have about +1 per 5 levels. This way if one character has the gold of a 15th level character and one has the gold of a 5th level character(which is likely a HUGE difference), the difference in magic items is only +2 to hit and damage.
If you remove the number of things that purely add to your attack, ac and saves, AND reduce the number of slots you can put things in, it further reduces the dependency on items. However, it's a long shot from "No one needs magic items so why bother putting them in the DMG or releasing a book about them."
