A stronger presence at E3 (or at least a dozen Nintendo directs) would do more for Nintendo's global presence then this bizarre stunt at Rio. At least at E3 Nintendo would be assured that gamers and the enthusiast media would be paying attention. While at Rio, it's a mix bag and nobody was watching the closing ceremony anticipating co-branding with Mario. Really, Nintendo at Rio seems like a continuation of their failed 'blue ocean' strategy, trying to chase the casual crowd that made the Wii a success without realising that the industry has moved on.
Are you saying that the Olympics gives you less exposure than E3?
