This game seems to have pretty low expectations considering some of the data released recently.
NPD for 2007 has MP 8 selling 1.82M Media Create has MP 8 selling 1.15M at 01-06-08 ELSPA gave MP 8 a platinum sales award, which means the game sold more than 300k but less than 600k in the UK alone.
So that puts the game at least at 3.27M already without taking the rest of Europe, Australia and Canada into account. This should put it at least around 4M worldwide now, without a new Mario Party being announced yet. That leaves quite a lot of room for increasing its sales in the coming year and the current expectation of 4.5M seems pretty low to me.
