What direction should/will the Metroid franchise take?

If DKCR sales are through the roof, then I'm fully expecting Metroid to go sidescrolling again.

I don't think one will have any real bearing on the other.  It's not like Retro's Metroids outsold Sakamoto's recent non-Metroid hits either (Rhythm Heaven, Tomodatchi Collection).
