What analyses / comparisons would you like to see?

[Game_boy]

I would like to see more in-depth predictions for sles over time, instead of having to work out them from weekly sales e.g. at this rate Wii will reach 10,000,000 units in x days. Some of the news articles have made predictions about Wii catching up with Xbox 360, I find that interesting - if you could factor in holidays I'd like to see what the results might be in a year's time if nothing changes.
