1UP got their hands on both the PS3 and 360 versions of DMC4. Here are some of the things they mention about their experiences with the two games:
"The first thing I noticed, the PS3 version looked better"
"You can tell this game is built on PS3, being moved over to the 360"
"I noticed some screen tearing on the 360 version"
"The moves are easier to pull off on the Sixaxis vs the 360 controller"
They also mention how they are excited about how Capcom is now ramping up their next-gen development. DMC4 is using a brand new engine that isn't just "up-res PS2 kinda stuff".
In addition to that they believe that DMC4 is looking better and more interesting then Ninja Gaiden 2, which isn't using things such as on-the-fly weapon and stance changing, and which doesn't look as visually impressive. They are also of the opinion that the combat system and gameplay overall will probably be better in DMC4.
Furthermore they mention that this outing in the series will be more user-friendly and more mainstream. It won't be "so fricken hard".
They do wish however that the tone of the narrative had changed "As much as I like the DMC series the story and cut-scenes are just laughable, the same stupid bullshit".
Could the PS3 version be the definitive version? I wasn't excited about this game much to begin with, but after seeing all the new in-game videos I'm starting to get interested. I have never played a DMC game before, but I really liked the Onimusha games, so if they are anything alike, I'll probably love it.
