Over on the Diablo 2 page of Battle.net, there's some information about the long, long awaited 1.10 patch for the title including that it's currently in QA right now. Here's just a taste of what all they posted on there:

• More Challenging Gameplay - Diablo II players who adventure in the Nightmare and Hell difficulty levels will experience a world in which the monsters have become more powerful and substantially harder to defeat. Players may need to develop new tactics or enlist aid from others in order to face these strengthened minions. The monster improvements include enhanced AI, more skills, greater damage, and higher resistances.
• A New World - Players can expect to encounter more randomly distributed unique monsters in every locale and even a few guest monsters where players wouldn't normally expect them. In addition, characters above level 70 will require increasingly more playtime in order to gain levels.
• Enhanced Skills - The skills of each player-character class have been thoroughly revised. On top of that, a new system of "synergies" has been added to each character's skill set. Allotting a point to certain skills will result in synergy bonuses to one or more of that character's corresponding skills. After the patch is released, visit The Arreat Summit for more details.

Let's hope they fixed the skills so that putting points in a lower skill can augment greater skills instead of them just being replacements, therefore a waste of skill points later on.
