I actually feel the opposite. As consoles became more expensive to develop for, the types of games that aren't considered cutting edge (turn based JRPGs and dungeon crawlers are a good example) got relegated to low cost handhelds like 3DS and PSP. Now that the lowest baseline is gonna be at the very least on par with Wii U, will games like Etrian Odyssey, Bravely Default, and even top down Zelda still have a place?
Instead of the mobile->handheld->console hierarchy we have now, if switch does to 3DS what DS did to Gameboy, that middle handheld tier is completely gone.
