As of recent you have been handling all the attention from the media suggesting you are making a move towards mobile gaming. Although you deny that this is the case, this is something you should seriously consider. I would even suggest that you also aggressively seek to make your games available for the Mac and PC as well as tablets and smartphones.
Consider Rovio’s success with Angry Birds which is similar to Super Mario Brothers; they have been successful putting their games out on tablets, desktop computers, mobile phones, streaming video players and even regular old consoles. No matter the technology, those birds are there for someone’s enjoyment. You can’t say the same for Super Mario Brothers.
Mario, your mascot and a legendary character from the best-selling gaming franchise of all time, is still largely available on your stationary and portable console systems. Dismissing such an opportunity to expand access to your most trusted brands (even Zelda) would be sad. As you are no doubt aware, there have been emulators available for many years that have allowed your products to be played on desktop computers (for example Dolphin, which helps Windows/Mac users play Gamecube and Wii games).
Part of what makes your company work in my opinion is that you like to cater to all ages. You don’t rely on just niche gamers who flock to a certain type of game. You understand there’s a need for a game like Wii Tennis (and Wii Fit) where everyone can join in and no one gets left out.
I would send your people to Amazon, Apple, Steam or even Roku and get those games into other markets with all the power you can muster. Since there is a demand for retro gaming, you should consider selling your classic titles such as the original Mario Brothers NES trilogy which is still popular today. You can put together a separate team, so as not to make the main development team do all the work, that can re-code those games for those other markets.
Should this work out, I would imagine you would no longer need to make consoles. The console base of customers you have may be disappointed, but successful businesses are about change. I am sure, as innovative as you were in the past, that you can be that again.
