Bioward has announced that they are in early stages of development for ME4. No specifics on platform, but I assume it will will also release on Wii U. If you don't count it, just count The Last of Us at #5 and shift the other games up one.

I'm really tempted to write Final Fantasy XV (Wii U) in the list, I have heard rumours that Versus XIII has become FFXV for a Wii U/ PS3 release.
