Is it a good idea for Nintendo to move away from the casual market?

No way, because in certain/many instances, Nintendo has proven that they can make a lot of money from selling to casuals. Equally, if you cater just for the hardcore, no matter how good your game is, it still has the potential to undersell. I think there were a few hardcore games that undersold this year 2012 - no?

I would agree, however, that Nintendo should focus on selling certain games only to Westerners, and where they cannot make such games themselves, maybe because they just don't have the time or will, they should then be in the business heavily of publishing those games as Nintendo exclusives.
