The strange thing is, MC, BWL, and Naxx bosses may actually get stronger than before. I was browsing some other forums, and at least during the beta people found that "skull" level bosses actually had their combat mechanics scale with the highest level players in the group! What this means is that miss rates, resist rates, crushing blows, etc. from "skull" bosses always seems to be calculated as though the boss was highest player level +3. Total hitpoints, and damage done, didn't seem to change, but one (probably unintended) consequence was observed. As most people know, things like crit rating, armor rating, etc. have less effect against higher level monsters, and as a player levels it even has less effect against like-level monsters. For instance, if a tank had 67% damage mitigation at level 60 against level 60 mobs, then at level 70 (with approximately the same armor) he would have only in the mid-50% damage reduction against like level. And since the "skull" boss would now be level 73, he is going to hurt you more. Many tier 3 guilds have noticed that their tanks, still wearing the Dreadnought from Naxx, have actually been taking more damage against the "skull" bosses!

What this means is that, although the dungeon trash is no doubt easier, many of the bosses in the raid dungeons will still require a well coordinated group of probably at least 15 level 70 characters. So, although the level 60 raids will be easier, they have hardly been made trivial yet (assuming that all of this boss-scaling proves to be true, and Blizzard has actually intended this).
 

I know there was a video about a 68 paladin soloing Strat in beta somewhere...
