Next Lumia Dual Sim

[Sonu K]

Lumia 630 is the first dual sim phone in WP OS. Does anybody have any idea which will be the next dual sim lumia? (I know Lumia 638 exists, if we can consider it as a different device. But what's next?) Lumia 730?

But doesn't it look like it has old style buttons below screens and not the display buttons like in L630? Might be an old scrapped concept, don't you think?
