The only issues FFXIV has because of the PS3 is UI stuff and that is only because they don't want an unfair advantage. I expect by the next expansion they will stop caring that the PS3 can't keep up.

The Xbox is plenty powerful enough to run FFXIV and not restrict it. I still don't understand how people who say they know so much about computers don't understand the difference between consoles and PCs. Yes consoles run on older hardware but they are designed for gaming and gaming only. They don't have to run a resource hog of an OS in the background. On top of that the engine can be optimized far better for a console than it ever could be for a PC because PCs are running different OSes, on different CPUs with different GPUs and different levels of RAM.

You can also bet they will not be pushing the game past its current base requirements because that could mean losing subscribers. Extra eye candy that is unlikely to increase sales at the cost of development time and paying customers just isn't something developers are into.
