Just saw this thread - the concept looks very interesting. I guess EA has bought all the licences back to 1999, and is still free to use them. Shouldn't be too much work for EA, it's probably just F1 2002 rehashed with the old seasons put in. Four years isn't really that much, having 1998 would mean then entire 'grooves and narrow track era' would be included.
Still, it'll be sad lining up in 1999 and looking sideways and seeing a Prost, Stewert, Benetton or Arrows
