According to one of our Admins this may just be the GT-I9500,and the useragent seems to hint to it.
Well the device seems to have a metal border with metal buttons and it seems that this device is the same size as the Galaxy S2.
Also the home button apparently needed replacing, instead of the rectangular shape it is a square shape now.
One thing is certain it support a frontfacing camera and it has a large speaker on the front. And it looks like that device will have a shutterbutton aswell.
The render we are talking about from Tizen SDK:
* Is this weird?
No in Samsung's own Bada 2.0 SDK had a render of the Wave 725 in it.
In February we will know for sure.
