If it has not become readily apparent with the incredible success associated with recently released title's such as Game Freak's Pokemon Black and White 2, Nintendo doesn't really care to cater an older generation.
It can be shown in their static resilience to provide the same games from first party developers over and over again and quite, frankly, forget(?) about a large part of the video game market (18-34 year olds) who would rather engage themselves in more mature titles that speak to them on a higher level than say, Super Smash Bros. or the latest Zelda.

- "Are you… a… a gamer?"
The fact of the matter is that this business model works.
Nintendo has brilliantly supported this practice for years and it is apparent that it is working. Hardware sales and first-party title sales top the charts month after month with only a few minor hiccups every now and then according to vgchartz.
Nintendo knows what its doing however for the millions of gamers who got their start on the console, moving on to let a younger generation take their place may be a hard thing to do.
