I liked how dragons dogma handled, all the moves you could do.
But was it better than Demons or Dark? No. I do wish your character had a wider move set in the Souls series, but its the better game either way. Will have to see if Deep can compete.
A movesw set doesn't make a game. Dragon's dogma does not have any online modality except the one against Ur-Dragon (in dark Arisen ver.) where the co-op is desynchronized, you can select some pawns of players and then go into the raid of the DRagon location.
Demon's Souls by its side has co-op, versus and the extraordinary either complexity and accessibility of the battle system, nothing like compare to the low pawns AI, you can choose your own style, there are not pre-fixed special moves, you make them with your skill.
In the way that Atlus will release Persona 5 on PS3, next year, they know their market and where the sales will be. They are a small developer and publisher, although Namco has the publish rights on DS2. If they sell enough PS3 copies they might port it for next year. But if it was up to atlus, they won't likely do it.
