There's no benefit to not releasing many iterations of hardware these days, especially mobile hardware. If you're not releasing a lot of iterations you're simply leaving money on the table.
IMO though I have some doubts about Nintendo releasing a Switch without proper Joycon support. They want people buying those Joycons, they probably have some controllers specific to games in development too that are dependant on the modular Joycon design of the Switch.
