Please reconsider making this go live with 4.0.1. ICC 10 and 25 are still different difficulty levels, and award different items for loot. They have separate achievements, and many players are working towards separate achievements at the same time, and need loot from both instances. Making us choose one or the other before cataclysm is NOT a good idea.
