Well 500k on every console is a decent result, however on the Wii development costs are significantly lower so financialy its usually a great success, like other said developers are usually very happy with sales around it ex. Suda and NMH or THQ and De Blob (they must be pretty exited now since the sales have picked up)
About Madworld it will definately reach 500k, it's as interesitng as it gets, SEGA will advertise their game and gamers will buy it, 1 million is certainly a possibiltiy.
About The Conduit this is the most hyped Wii Game from 3rd party studio, it's bee na talking point for months, supported by majority of gamers and HVS has been doing pretty good job, if the final product is decent/good enough it will definately sell more then one million.
