Apparently someone on NeoGAF posted a quickie translation of the recent Dengeki review. It's terrible, so here's a cleaner version of it:

Dengeki Review: Dark Souls - 90/90/95/95 (out of 100. Compare to Demon's Souls - 85/85/85/95)
High difficulty that rewards a smart, cautious playstyle and punishes typical gaming skills. This isn't a game for everyone, but it displays a seamless, load-free and atmospheric open world to explore that showcases enthusiasm from the developers.
Tense gameplay made for fans of Demon's Souls. Leveling up can relieve the tension some for players who are bad at this type of game.
The game is designed to defeat players with difficult enemy locations, narrow areas and clever traps that can't be evaded the first time. Limited healing makes this a difficult game, especially for new players, but it's very rewarding when you finally complete it. Not for people who dislike gore.
A refined Action RPG that requires players to learn from each death and develop new strategies and techniques while also showcasing great graphics and cutscenes. A difficult game for beginners, but it has plenty to offer them if they choose to stick with it. There wasn't an opportunity to play the game online, but the offline mode alone is attractive enough.
The Good:Completing the difficult challenges is rewarding and the upgradable weapons and armor are fun to collect.
The Bad: Lots of grotesque enemies.

Play Report
- Mr. Raider 1
Even low level enemies are difficult and have the ability to climb ladders.
Reserving your healing items for a boss fight can put you under pressure.
The difficulty makes Demon's Souls seem cute.
- Mr. Danishi
There are many places that can kill you. There are certainly traps, but you can be ambushed as well!
Groups of enemies are scary. If you don't handle them well, three skeletons can be far more fearsome than traps and dragons.
Numerous seamless environments.
- Mr. TDB
Played for more than 20 hours.
There's ground that breaks when you walk on it.
The high difficulty makes the game satisfying.
- Mr. Raider S
I'm bad at action games and couldn't clear the demo, but watching other people play is fun too!
High places can make you acrophobic.
I swear to complete the demo!
