Capcom seems to be making decisions aligned more with consumer interest in mind than they were toward the end of the PS3/360 generation. Not sure why or what happened, but it's very much welcomed.
I would assume it happened because they had to port the engine for DD:Online to PC in the first place, and since the game seems to massively reuse everything from the original, I guess it wasn't too hard to make a PC port of the original, which will let them both make money and test the waters for a western release of DD:Online(which sadly so far looks kinda garbage, especially if you've played the original already since it reuses everything with very few new things and a lot of things removed). I don't feel it's a coincidence this is being released only a few months after the DD:Online japanese beta started.
The good thing is the PC client isn't too bad for DD:Online, from what I've seen. I don't customize graphics stuff too much though so take that with a grain of salt, but the game ran well and didn't have any really weird features that some port have, at least that I've noticed. I guess it had a 30FPS/60FPS toggle with no other options, so 60FPS might be the best you can get, but that beats 20FPS on PS3 anyway(or 5 if you played a mystic knight in combat).
Really looking forward to this, I played through the game twice already(vanilla then dark arisen) and I've played almost every class, but I guess I'll just revisit it again. Just need to figure out a class. I kinda hope they add some balance stuff to the game also but not holding my breath.
