The A380 is timed perfectly. It will fly just at the point that demand reaches the level where 500+ seaters are trully needed. Making a big transport isn't like putting out a CD, where you do all the hype up front and get as many people to buy it in the first week so you go into the charts high and watch it then slide down the charts. Airbus need a product that will sell for 20 years+ (like the 747) so if they size it to cater for the market now, or even in 2006, by 2015 it's going to be too small. They may not get much past 100 orders til (say) 2004, but the first flight will still be 2 years away. Then the recession will be receding and by the first flight, orders will have jumped to 300 (say). I bet that including stretched models, by 2015 they're past the 600 mark.
