I think the charts are useful - but yes the industry is prone to big spikes and swings so of course they are only tracking a moving target.
However they do show what common sense would indicate - that in a poor economy the only console with a modest rise in base demand is the one that took a big price drop vs two that held firm.
Of course if GT5 does hit this year and drives consoles like gangbusters the percetages could change by the end of the year, and of course there's the new Halo, etc. - but that's the fun of an industry where single events can have major impact.
Try to be reasonable... its easier than you think...
