The (near?) future will see the demise of the 510 connection. It was designed for cigalikes and is really not appropriate for anything larger than an eGo. eGo threads will not be the answer either. I think the future will bring a sturdy, multi-circuit (4+) connection to support new technologies. There will be 510 adapters available for use with our existing atomizers. I think we'll see the first change in connector with Innokin's forthcoming iTC.
