why ask such a silly question?
people are still massively interested in Nintendo's dominant handheld and just last generation Nintendo was the leader in home consoles
obviously the current issue is their actual system, people don't seem to love it. but the interest and following of Nintendo in terms of brand and IP's and characters is obviously alive and well
literally the majority of Nintendo consoles have been successful and most of them did not have THAT blockbuster of third party support
