Now that Metroid has underperformed, we'll probably not see a new entry in that series for another decade.

This is something that bothers me about Nintendo - they're not the least bit shy about packing Smash Bros full of affectionate callbacks going back to the early 80s and franchises nobody under 50 would recognize, but they still consider these franchises not worth a mention otherwise. Ice Climbers, Kid Icarus, Punch Out, Starfox... All of these could be great again if they'd put off another Kirby game to revisit them.
