I think the variation in game price points might be a good thing for the Switch. It would be a good indicator of what kind of content you'd expect (in terms of length and graphical prowess), while keeping cheaper titles from looking like they have less worth. Like, a $30 box retail game next to $60 titles makes the $30 title look either like a) a bargain or b) crap. Yes, there's some room in the middle, but the newer a title is, being at a cheaper price can hurt perception.
With Switch, we should see "full price" games ($60, Wii U; $40 3DS), "cheaper" titles ($50; $30), and prices below. Hell, you can break down the eShop in to $10 tiers.
