It's not only ZombiU, there is Mass Effect, Batman, AC II, etc. Even if most games are ports, they need to sell well in order for third party to even consider making new games for the Wii U. I see the GamePad kinda like the Wiimote, Nintendo and some other few other devs will be the ones that use it in really unique ways. The other will just put a map or inventory screen and call it a day (this isn't necessarily a bad thing, but we'll see this in almost every Wii U game, kinda like the DS/3DS).
I do agree that ZombiU will be a big part of the future third party support for the system, but if it sells a lot (let's say 2m) that doesn't mean other developers will jump right in. It will help, but it's not guarantee.
