it was announced like a year ago, at last year's e3 or tgs. and i wouldn't get my hopes up since it pretty much looks like ff11 v2 and ff11 blows. the reason no one mentions it here is because (hopefully) no one cares.
as a guy who still plays FFXI and has been watching FFXIV since it was called codenamed 'rapture' I think i can say beyond the similar graphics and familiar races the two games don't have much in common, beyond the stuff most MMOrpgs(and FF games) have in common anyways and even then, they've got a few ideas that they are hoping will make them stand out.
As for playing FFXI on ps2, its no problem as long as you have a usb keyboard(no mouse needed, in fact the mouse sucks on the PC version as well, most people use keyboard only or controller and keyboard on PC). Of course on the pc version you can get windower which can make the game a bit easier to play(and look way better).
