I think it'll be something along these lines;
Wii: 17 million, placing the year end lt sales at roughly 82 million, seeing the yoy drop before and during holidays (the record week not withstanding) leads me to believe it has peaked and is on its way down. I grossly overshot my 2009 prediction on the Wii and guessed 72 million by years end and I was on the conservative end of the scale when I made the call in December 2008. Won't make that mistake again.
360: 9 million, placing the year end lt sales at roughly 46 million, it'll have a good year but I do think it has peaked as well since it is a full year older on the market and prices are really, really low already. Predicted 36 million by years end of 2009 and ended up pretty damn near and I'm confident that this number is also quite close.
PS3: 14 million, placing the year end lt sales at roughly 45 million, the best year it will ever have but not by oodles or miles, FFXIII and finally GT5 will have completed the release slate of the flagship titles from previous gens and leave decent sustained hardware sales this year I think. Hit the nail on the head by predicting 31 million lt sales by end of 2009, a feat which was not only deemed impossible at the time (December 2008) but would make people point and laugh.
PSP: 7 million, placing year end lt sales at roughly 62 million, going down, down down. Missed my 2009 prediction by 4 million, thinking it would sell 59 by years end. I misjudged the impact the new version (s) would have and the importance of the surge in Japanese sales.
DS: 19 million, placing year end lt sales at roughly 142 million and damn near best selling console ever which it will cross shortly after that, finally settling down and starting to slow after many years of not only thrashing anything and anyone opposing it but also most people's expectations. Missed this by 2.5-3 million (guessed 126 million by years end 2009), not precise but still a whole lot closer than my Wii prediction.
To sum up, by years end;
Wii: 82 million
360: 46 million
PS3: 45 million
PSP: 62 million
DS: 142 million
