I edited the previous post with this part to highlight the massive achievement Nintendo got in those 5 years:I don't mean to sell it short, but 4 years is not a particularly long time. It was recording breaking though, and an immense resurgence for Nintendo after about of decade of the N64-Gamecube slump, which highlights just how much they shit the bed on entering the next generation on both fronts.
What I mean is that , despite Nintendo got an operating income of 529 billion yen between 2001-2005 (very very good profits for a VG company, more than SCE in the comparable timespan), in the period between 2006-2010 the operating income boasted to more than three time that, at 1796 billion yen.
A gain simply unheard of in the videogame business and one I doubt a videogame company will replicate again.
EDIT:
The "resurgence" lasted an entire generation (a meaningful timespan in the VG business), sure Wii was abandoned after 2010 and DS was hit heavily by piracy in the latter years but the whole generation was a big win for Nintendo (and of course it was noteworthy only a fool would say otherwise).
Should we acclaim Iwata (or Nintendo more aptly) only based on that period?
Of course no but fuck ups are to be expected as fortunes are volatile in the business (and fuck ups happened even during the DS/Wii days...).
Nintendo will go through hard or lucky periods (as it did in the past) with or without Iwata.
