Wait! Before you post that stinging comment before even reading this piece, just take a second and let me explain.
I am not saying that Nintendo should get rid of the DS or Wii and only have one console on the market. I am also not saying that Nintendo is going to fail with either console in anyway.
So, what am I saying?
When I saw the list of games that Nintendo and its partners have developing for the 3DS my heart almost seized with excitement. Pretty soon after, however, I also started to wonder why I wasn't getting a game like Pilotwings on my Wii and why a game like the reboot of Kid Icarus is only going to come out on the 3DS. So, I am saying that Nintendo might profit from developing their games like they only have one console.
Since the 3DS is a powerful machine, Nintendo should easily be able to port the games being developed for it over to the Wii, make some additions or changes to make the games fit onto a larger TV, and then reap the benefits of selling these great titles on two consoles!
I also think the same mindset might profit Sony when they are thinking how to develop games for the PSP.
Now, I know that not every game would be a great fit for both a home console and a handheld, but I do think that the vast majority of the titles I have seen being developed for the 3DS would feel just as good being played with a Wii Remote as they will be with a stylus.
It has always seemed to me like Sony and Nintendo have trouble keeping their eyes on the development cycles of two consoles. At times it feels like they have to choose which console to give the short shrift, and right now it seems like Nintendo has cooled on the Wii (despite a few good games on the horizon, E3 was almost all 3DS). I truly believe using this mindset could profit all of the consoles and games these companies juggle.
