Like any analyst, their predictions aren't perfect. In fact, many abide by the 51% rule; if you get at least 51% of your predictions right, you're a good analyst.
Getting the full picture in 2008 on how the consoles will sell is a lucky guess. Not more.
Wii U could theoretically still outsell the Wii if something unpredictable happens. Xbox 360 could outsell Wii or sell less than PS3 or more PS4 could sell 200 Million LTD and Durango 500 Million.
Ofcourse its rediculous now what people said in 2008 but in hindsight its easy to talk.
