Actually the lack of HTTP access as well as the locking down of the Xboxlive system so that it can not connect to the internet or to other systems outside of XBL is exactly why XIV wont show up on the Xbox 360. Microsoft does not want any game on its system to cross platform with PSN. Or Steam. Which is why steamworks is getting ported to the PS3 and allowing PS3 owns of Portal 2 to instantly own it for Steam as well.
