Upcoming Low-end device with "Microsoft Lumia" Branding leaked

Microsoft recently took the Conversations blog to detail the changes that are going to happen in coming months. One of the major change that is going to happen, is the removal of "Nokia" from the Lumia devices. Instead they said that they will use "Microsoft Lumia" for the new upcoming devices.
Today, an upcoming low-end Windows Phone device with Microsoft branding got leaked on Chinese forums. This device named RM-1090 has passed certification of Ministry of Industry and Information Technology (MIIT) of the Chinese government.
During the re-branding announcement, Microsoft announced they will be sharing information about a new Lumia device soon. This could be the new Lumia device and by observing the design of it, I guess it could be the successor to Lumia 530.
 It lacks camera button, but includes a front cam and I hope Microsoft has upgraded its RAM to 1 GB.
