This is a day one purchase regardless of reviews.

As far as what they can improve, I'd say:
1. Rework the online component. It just needs to be easier to connect with your friends. All they need to do is make a party type system rather than making players drop soul signs to get summoned.
2. Less glitches, particularly how you can kill some bosses with cheap tactics (Maneater and the False King come to mind).
3. Improved balance- At first, Demon's Souls seemed very balanced, but, as I played more, some of the problems became pretty glaring, particularly in PvP.
4. Combo variation is always welcome as well. Demon's Souls is fun, but it would be better if there was some more variation in what combos you can use.

With that said, this is still my most anticipated title, and I plan on pumping a lot of hours into the game.

Because they give it a good score.

Apparently Japan (Those damn Japs(No racism lol)) gets it this month on the 22nd, and they can't just release a written review for us to translate too, it's like they want me angry =l

Lol well if thats the case i'm sure some American reviewers will get to review it early. So about a week more before you get an actual review you can read?

You should go to youtube and go watch some more gameplay and trailers to hype you up.

Will do!

Ya I suppose that makes some sense, maybe 2 weeks at max? Still hyped, though this supposed to keep me busy until Zelda!
