Nokia 5900 Xpress Music in the Pipeline?

Is Nokia Planning to launch a successor to its Nokia 5800 XpressMusic Phone?
A Chinese Website has released some pictures of the speculated 5900 Xpress Music Handset.
The device seems to have a similar form factor as the 5800, but has a grill pattern on the front fascia. The device shown supposedly sports a 5 megapixel camera, 3.5-inch touchscreen and a 3.5 mm jack.

Apart from these pictures, there aren't any other indications of this one actually making it to one of Nokia's manufacturing plants.
