The lower development costs will also be attractive.
Graphics are such a huge part of any developers budget these days that if they can get a decent install base on a cheaper to produce for system they will make games.
For a long time now portable games (Gameboy, DS) have allowed for greater returns on anything that isn't AAA
Nintendo just gave them license to develop cheaper games and charge a higher price for them. So long Z the games are a decent length people will pay.
