I wonder what type of applications will come out of this.

For example, I want to build security cameras with Raspberry Pis, but I don't need audio output, USB, HDMI, etc...but I would need WiFi, camera unit, and power. But I doubt we'd see custom IO boards for specific applications such as this, and I don't think it'd be any cheaper than just buying a regular Pi.

Well, just custom-build a PCB. Either laserprinter-etch it yourself or use one of the maker services. If you're just after USB (for the wifi) + camera + power, you don't need that many pins so you can solder the SMD SODIMM socket even by hand.
