Hi All, I figured this out finally.
I should mention that I got a clue here, albeit not one that I understood:
http://forum.unity3d.com/threads/unity-3-2-update-too-many-texture-interpolators-in-triplanar-projection.78579/
I needed to build my own normal variable and get it through using a vert program and changes to the input struct, using the one that's there already freaks out unity (a fixable bug?). My new normal stuff is ccalled "myNormal".
Shader "gamevial/TerrainWorldMapped" {
Properties {
_Control("Control",2D)= "grey" {}
_Splat0("Texture1 (R)", 2D) = "white" {}
_Normal0 ("Bump1 (R)",2D)="grey"{}
_Splat1("Texture2 (G)", 2D) = "white" {}
_Normal1 ("Bump2 (G)",2D)="grey"{}
_Splat2("Texture3 (B)", 2D) = "white" {}
_Normal2 ("Bump3 (B)",2D)="grey"{}
_Splat3 ("Texture4 (A)", 2D) = "white" {}
_Normal3 ("Bump4 (A)",2D)="grey"{}
//_MainTex ("BaseMap (RGB)", 2D) = "white" {}
//_Detail("Fallback Detail",2D)="white"{}
_Scale ("Texture Scale", Float) = 0.1
}
