I am a bit miffed that they seem to be using only a slightly updated version of their PS2 engine (which wasn't anything fancy in the first place), but apart from that this game looks awesome. Going by the 'Battle' video on the official site, it seems like the hack-and-slash action will be similar to the Onimusha games, if not better:

I don't expect it to have the deepest fighting system yet, but as long as it's reasonably technical I will be content. This is supposed to be an adventure game, after all. It's also the most promising exclusive PS3 title I've yet seen (not counting MGS 4, which will likely not be/remain exclusive for long).
