I mean, PES is pretty damn major, the Wii versions tend to score 10 points higher on Metacritic than the 360 versions (haven't checked the other platforms but I think they're the same as the 360). I don't have sales numbers but it wouldn't surprise me if the Wii version sold more too. So why does it come later?
EDIT: Just checked, if VGChartz is to be believed on this (questionable since the vast majority of sales is in the "other" region and data on that is spotty at best) PES 2009 sold 2 million copies on the PS3 and only 290 thousand on the Wii (previous year was 1.7M to 1M, did they **** up tracking it or did the 2009 edition really see such a severe drop in sales compared to 2008? If so, WHY?). Serious WTF there, definitely can't blame that on the quality. You'd think traditional PES would suffer much more from FIFA's rise in quality than the RTS-y Wii version.
EDIT2: Checked the release dates, PES 2008 had the Wii version only 6 days later than the others, PES 2009 had the Wii version 5 MONTHS later. Didn't know the delay was THIS huge, no surprise it's fucking the sales. The PS2 version sold the best BTW so HD is not the deciding factor.
