Is Amazon.co.uk incorrect in saying that 8 January is the release of Wrath of the Lich King - heck yes they are!

Vivendi in a press release indicated 1st half of 2008--announcements of that nature usually mean the very last day of the first half.

And Blizzard has in the past pretty much delayed any game they felt wasn't ready--missing holiday shopping season whenever the game wasn't done. So all dates are made up dates until Blizzard releases one.
