No, you're absolutely correct, more people do want to play Super Mario than Angry Birds, but more people do not want the hassle of getting a ROM, learning what the heck a ROM is, etc. That Nintendo and the other companies haven't dedicated a small team to native Android / iPhone development to make some small games for the phones surprises me.
It seems to me the other companies are coming out with native ports (sega, atari, capcom, square, etc.).
OTOH how can it be surprising that Nintendo is not cutting the legs off it's own platforms? 25+ years I can't recall their first party titles on anything but Nintendo consoles.
The games are the unique value proposition for their consoles (which they sell for a profit, unlike other companies). Publishing them elsewhere would quite probably be a net negative for Nintendo.
I agree, but I just thought it was always a strong strategic move for Android because all the people who wanted to play Donkey Kong or Zelda would at least have the option to do so, whereas for iOS you have to jailbreak your device.
