Whether or not you've been waiting for proof, you'll be glad to hear that Google now plans to hold its second Ara conference on January 14th. The focus will primarily be on the module developer kit, but there are also plans to show newer phone prototypes and provide the first hints of how the pilot launch will work. NK Labs is already willing to provide a small clue; it says that the next major test unit, Spiral 2, will give module makers a lot more room for their projects. In other words, it's likely that the next wave of Project Ara components will be more powerful than what you've seen so far.
