The original ffxiv 1.0 ran like a dog on my computer, and it was a pretty high end one at the time, although a year old when released. It's one of the reasons i quit, besides the real lack of feeling like there was a point to playing anymore. Yeah, looked great at the time, if i maxed everything and got 10fps. To be playable to me i had to lower to close to half or less settings, and it looked average then. This game runs great maxxed for me now, and i realize not everyone has as good a computer. that's the point, the more people that can play, the better. I do hope they upgrade the graphics at some point, there are some oddities i don't get, but i'm happy. Look at WoW, being able to be played on even relatively low end pcs has helped them more than hurt them.

Also, concepts are never real life, it's to show a feeling, or an idea of what the goal is. I'm betting not one thing in the concepts are even animated, using higher mesh models, effects, all that. Just compare to concept cars shown at auto shows, you will most likely never see one hit the road for consumers, the only one that really has is the New Beetle by VW, mostly because it wasn't as over the top as most concept cars. Same in gaming. Only upon release will you know what it really is like.
