I got the impression that combat would still be relatively simple, or at least that it didn't go the 57 button route.

Not much has been mentioned on the system specs, either, except they are targeting to have it run on Geforce 7800 video cards. Because it is being made for the XBox 360 it will not require a lot of memory (though of course more is better). They have not mentioned CPU, but anything remotely recent is usually good enough for most games.

My current system is also below the requirements, but as upgraded as it can be. I was thinking of getting a gaming laptop fairly soon, but am now leaning towards waiting until mid year (a month or so before release, whenever that is).
