I dunno. Nintendo is very slow to move. They have their own philosophy and do things there way...and sometimes that means they are very slow to move with the times, and make the appropriate decisions to advance in the current market environment.
However, Nintendo has been making smart choices this generation, and are learning hard lessons in the areas they slip up. The Wii and the DSi have had great success, but also very painful failures and Nintendo seems to be learning from those lessons...
the above statement says nothing to the fact that Nintendo hasn't been studying the market and looking at the future. Nintendo Japan has already stated that Apple is a serious competitor they are looking at in the future. Nintendo is looking at the future and I believe they will continue to grow.
Am I foolish to believe Nintendo will magically learn all their lessons at once and make a perfect system with all their previous mistakes corrected? NO. I don't...I believe the Wii2 and the 3DS will still have issues, but it will be better. Actually, I honestly have to say the best system built and the most complete console ever built was the Xbox 360...but even that had problems. But, the overall product was solid.
I hope Nintendo looked very hard at Microsoft and what they did right this generation.
