What we can safely assume as Lumia 530 has been leaked in images in China. While the source article reads it as Lumia X, it does mention it as the lowest end Lumia device. It will have on-screen touch buttons and will lack a camera key as is expected and is clear from the two images.
It is thicker than Lumia 630 and as revealed today by us will come in both dual-sim and single sim flavors. It may sport a 5 MP camera without flash. We have already reported Lumia 530 passing certifications in US and Thailand as RM-1018 and RM-1020.
Thanks Xio-Feng for the tip. Cheers!!
