As i said somewhere already, i expect their strategy for n3DS exclusives to be -- "increasing sales of underperformed console installments by porting them to handhelds".
I fully expect Tropical Dong on n3DS this or next year. They only thing stopping them from doing it on regular 3ds was lack of power, well now they have it.
This also stops console games that are still selling from becoming obsolete -- you don't feel the sting if it's "just a port of a game i already have on a console".
