I JUST GOT MY WII FIT ! ! ! I ' ve been calling every day for two weeks and they finally got them in . I went running up ( luckily , mall 5 minuts from work ) and snagged the last one . They got 12 - sold out in hour !

Question:
Why has it been so difficult to get ahold of a copy of Wii Fit ?
Pick from:
(I). Everyone wants to try it and is buying it up as soon as they can;
(II). Wii Fit is difficult to translate to the speakers native language so supplies are scarce;
(III). Wii Fit is difficult to source in this town due to exceptionally low demand;
(IV). The speaker has been trying to save up the money to afford a copy of the game;
