Item quality can really be summed up to how long it takes to replace the item. All items will be replaced, but the quality of the item really boils down to how long it's going to stay on your character. Now that can definitely be altered drastically if a person is suddenly progressing really fast or jumping around a lot, but in a linear sort of progression (like leveling) the item quality will generally equate to how long you have it.
That's still very much true going forward, but what you won't see is someone going into Howling Fjord in tier 6 and seeing it replaced with quest rewards. That said we still want players to be able to progress, and to get new items, because while everyone becomes attached to their items to some degree you're ultimately trying to improve them, and never getting an upgrade would make it really boring.
Also while there still has to be some amount of 'catching people up' with a level cap bump so that we can appropriately manage difficulty, I don't think you'll see quite the same disparity as you did between pre-TBC loot and post-TBC loot with the release of WotLK. It's way to early to say that as a fact or anything near it, but it would be my guess.
Also ... I think there's a thread around here somewhere with the title "Blizzard you care too much about raiders". Fun how that works.
