Three quick facts for you:
1) XIV Gen3s are now shipping.
2) Orders for XIV Gen3 are flowing in.
3) The XIV Release GUI is available for everyone to download and use.
Links for the GUI are here. My personal recommendation is that you uninstall the old 2.4.x GUI before installing the new 3.x GUI. Remember you do not need a Gen3 to use this great new GUI. It works just fine with the 2nd Generation XIVs. So get downloading and tell me what you think.
