Why Nintendo 1st party games hardly go on sales?

One nice thing is the games do hold value if you do end up selling the games. You can buy say Paper Mario for $35 at Gamefly beat it and sell it for $30 to gamestop or 30-40 on Ebay. One thing I'm not looking forward to is when Nintendo releases their next console and will probably follow Sony and Microsoft and start selling them for 69.99 with the games rarely going on sale.
