Assuming the price of the controllers is correct (from N-europe) the cost of the Wii is WAY too much, comparible with X360.
Cost of XBOX360 premier system in Australia has dropped to $530 AUD, wirless controllers about. $70 (on special even cheaper), old games dropping to $50 AUD.
Max cost of X360 with 3 extral controllers is $530 +3*$70 = $740 AUD
Cost of Wii with 3 extra controllers/Nunchucks is $696 AUD
So Wii is only $46 cheaper than X360, nothing when you consider cheap X360 games available, plus you get Hi definition, DVD player and Hard disk drive. ($140 cheaper if you add the much needed extended warrenty for X360)
Unless Nintendo drastically reduces prices after "early adopter" sales, it has lost the Australian market. Although I am willing to pay that much if Wii is successful, I am reluctant to do so and be left with another unsupported system (aka GCN) on my hands.
