It sounds like the dev kit is more of a way to get devices out to devs before the full launch, I'm sure you can develop using the consumer hardware. The Adam Savage Tested video had interviews with the Valve team and it was pretty clear that "it's your computer" was a core part of the philosophy.

> It depends though. Some console's devkit have memory or vram larger than consumer device. So it will allow un-optimized dev version of the softwares to run without crash. (And allow you to check what part goes wrong later instead of immediately fix it) Although you will need to test the production build on retail device eventually, it will make development easier.
