Lean supply chain management and contract manufacturing is likely the big upcoming trend in this space, as it is easier and cheaper than ever to have experts create the thing that you want or source the components or whatever.

I think the QA as well as fit & finish of 3D printing is not high enough yet (and unclear whether the investment to get to that point is worth it) for mass produced consumer goods. More likely it will spawn a big uptick in hardware ventures (already has) since it also massively reduces the cost of prototyping and can reduce the cycle time of early modeling and prototyping.
