It's not only Nintendo with a big porting opportunity here. Hopefully Skyrim's sales open some more 3rd party eyes. Particularly Rockstar's.I'm gonna get lynched by some people around here because of their concern about lazy publishing environments, but I think Nintendo has an interesting opportunity with the back-library of the Wii U. I'm someone who bought basically every one of the major first/second-party titles. I would be happy seeing more than half of those re-released on Switch; I think the games are that good and they hit a very small audience the first time around.
I think with the way the Wii U failed so completely, Nintendo may end up with a chance to make the first half of the generation's worth of their games suddenly marketable in a way that you normally couldn't at the halfway point of a system. That'll be hard to balance, because they'll need that steady stream of truly new software, but I think they can pad out their library in a way that'll make people happy.
These sales numbers are fantastic, but I think having a "captive" audience and being released so close to the launch enthusiasm, it's less of a suprise. They neeeed to take that initial enthusiasm seriously and have a plan for making their system feel like it could be a primary platform. The more oddball issues like their online chat show up, the more I think even relatively steadfast fans will start to mentally tally-up their frustrations.
