In this case, it may have taken a while for the PS3 to start outselling the Xbox 360 because of a little problem called Red Ring Of Death which killed a lot of those consoles outside of warranty, leading to replacements being bought.
Also in Germany, there are aerobic digesters which are fed by maize (corn) rather than waste and so the same argument would arise over growing crops for fuel or for food as applies to biodiesel production and must ring an eventual death-knell for both biodiesel and biogas, if the latter is made from food too.
