This also bring up the question of money, with getting our 'magic' bonues from stat increases we don't have a much we need to buy so wealth levels will probably be lower too, but then again stat boosters weren't all the magic items normally bought, there are Quiver's of Elhonna, portable holes, skill boosters (like a ring to boost Hide/Move silently), etc.
Yeah, wealth levels should be substantially lower. You won't need to buy stat boosters, cloaks/vests of resistance, and magic armor (or other AC boosting equipment). You will be able to buy some pretty impressive weaponry, but it largely won't be magic (or at least, that's not where it'll get most of its punch from). But the items outside of the magic item compendium's 'big six' (weapons, armor, vest/cloak of resistance, ring of protection, amulet of natural armor, and stat boosters), I'm not figuring on dropping any mechanical replacements into the game.
It's also probably true that most of the magic items you end up having will, in fact, be the sort of inexpensive (to mid-level 998YK Eberron adventurers) utility stuff that was very commonly made, and so lots of ancient (but still working) copies exist. But since this Eberron lacks the magewrights, artificers, and even wizards of 998 YK Eberron, newly-made stuff is extraordinarily uncommon.
