www.guildwars.com has these as of October 13th. A mere 6 days ago.
www.plaync.com has these as of...I dunno when.
I have checked a few websites selling the game and they have different system requirements. 2 examples would be: Newegg has guildwars.com requirements, yet amazon.uk has the plaync.com requirements. Oddly, most of the sites didn't mention any system requirements at all...

Anyways, I'm a bit concerned because I have a friend who is considering getting Nightfall, but they have a laptop with 512 MB RAM (64MB of which is used for video). Upgrading RAM or getting a new computer is out of the question for them at this time. Also just getting Prophecies or Factions instead wouldn't work because then we wouldn't be able to play in the same area.
I've watched some Nightfall videos and messed around for about 15 minutes on the PvE preview event, and the graphics/action didn't really seem like it would be something any more demanding or different from something seen in Prophecies and Factions...but maybe I didn't get deep enough into the it?
I truely hope the usual system requirements are the correct ones, as this will have a direct impact on whether or not my friend can play the game.
Do any of you know which are the true system requirements? Thanks in advance.
