2. Most of the "quality of life" features of current WoW, and existing addons, will be backported through addons and/or 3rd party services - Achievements, Gearscore (item level), Dungeon Finder, Boss Mods, etc, and will eventually become mandatory for everyone that wants to be competitive.
3. As a result of point 2, most raids will be puggable within 3 to 6 months of release. Yes, even Naxx. You don't even need an achievements for this - attunements serve the same purpose.
4. More people will quit at 60, because the game will be nothing as they remembered. Eventually the game will settle down with a small and loyal community, but it will have too few players for Blizzard to do similar experiments in the future (TBC/Wrath).
