mhm maybe- but I'd imagine the decent spec pc version (maybe not maxed out) will look much the same as the 360 version- and for most people I think the difference will come down to whether or not they'll play on a tv or a monitor.
TBH, if I have a decent enough machine I may well opt for the pc version myself but only if it's notably better. I don't have any notion that Deus Ex as a brand will instantly be made better for being on PC. It's a different world now, not to mention another developer.
