The Q&A mentions that the updates would be provided free of charge, but that doesn't rule out other charged microtransactions. Likely the update feature exists to fix glitches; however, graphical improvements and online capabilities would be a nice touch. Who wouldn't want to play Mario Kart online?
i remember reading long ago about how some VC games were supposed to get graphical updates, this shines some more light onto that, and hopefully we get more, this would really make VC worth it, and hell i'd probably get games i already got if they go ahead with this
apparanelty this is in the Wii shop channel Q&A so i'm gonna go confrim this before i head ot bed
