Those other new IP's aren't being developed by Nintendo, and none of them are planned for a US release. Not even S&P2 or Punch Out are being made by Nintendo.

No Second Parties? Then... Gears of War, Motorstorm, Killzone 2, Halo 3, Uncharted 2, Resistance etc aren't developed by Sony/Microsoft. Now my question for you is: Why does Microsoft and Sony take that long to make games?
