Sad to see an old friend down like this. I still have my NES and SNES and probably play both more than my PS3. Nintendo had a great run and they still have a lot of top-notch IPs but they kind of abandoned their the fan base that grew up with them when they came out with the Wii and now the casual gamers are moving on as well.
The entire traditional gaming industry is on the decline. It will be interesting to see where it's at in five years. There will always be a "dedicated" gaming base for the traditional games but production costs are getting higher while that base is shrinking.
