I doubt some of the lesser known tournaments from 2005 will be included, as the game is due for release in late 2006, but certainly the 2007 tournaments, including the World Cup.
What you all have to remember is that the game is still at the very early stages of production. Gameplay will be perfected before graphics and features. As you can see from last week's press release, progress is being made steadily.
Paul, alias legend_master, will obviously be very busy with the project over the next few months, so I'm sure with access to the website database and some random bits of information I could attempt to answer the questions presented at this thread.
