Nah stay away from fancy schamncy displays. You always can make an OLED (or 3D) display model later as an optional thing.
Go back to the philosophy of the SNES-GameCube of powerful hardware at affordable prices (rather than cheap/crappy hardware at cheap-to-not cheap prices).
Get AMD to give you a processor comparable to the Apple A9X or Tegra X1. That will allow developers to make a huge breadth of different types of games, even port their high end next-gen titles to in many cases (albiet at a reduced resolution).
Save money on the display by going with a low-cost 1280x720 HD display. Decent and nice (massive upgrade over the shitty 3DS display), but it doesn't have to be bleeding edge. You will save a lot of money this way.
