There aren't any easy answers with out first knowing the volume you'd potentially want to scale to and the end cost of the hardware. If you want to produce consumer devices there is the whole headache of molding etc. I'd honestly focus on making something cool with arduino (think ruby) and then when you need to mass produce go create custom PCBs. (think C++) The nice thing about the current environment is that kickstarter LOVES hardware projects, so you could quite likely crowdfund the scaling of your design.
