The best I can work out is that the new diaper is called the "MyDiaper comfort Weiß-bunt" (which translates roughly to "MyDiaper Comfort White and Coloured [i.e. Printed]") and seems to be made by the same folks as the Lai Yi Pian ones. Not sure if anyone else knows anything about these?
I've only noticed them today and a quick Google turns up nothing on the brand name. The only place I've seen them so far is SaveExpress / AirOliver and they've sold out (or have no stock yet) of the Medium ones. I've ordered some Large in the mean time and will post pics when they arrive.
As you can see from the pictures below, the diaper looks like a plastic/smooth backed product with printing that looks bit like the Buntewindel Fabine's or Cuddlz All Over Printed Nappy. The diaper itself is clearly different from both of those products and sports a wetness indicator and two-per-side dual-layer tabs which feature on neither the Cuddlz or Buntewindel products.
