These are the pros and cons from Cameralabs
It took a while but now you can preorder the new crazy good and a bit crazy expensive Nocticron 42,5mm f/1.2 lens at Amazon US (Click here). And these are the new lens reviews:

Unlike many fast primes that have come before it for various systems, the Nocticron is not about delivering a dollop of creamy bokeh at the cost of soft details once you move away from the center. It’s not about suffering from slow autofocus, nor having to worry about camera shake. It’s not about having to stop-down to achieve the sharpest results. No, the Leica Nocticron is about having your cake and eating it – and what a delicious cake it is too
$1599.99 is undoubtedly expensive for an 85mm lens for any system, but given the excellent image quality, creamy bokeh and snappy performance, we feel that it’s just about justified and a good investment for Micro Four Thirds users who require a fast portait prime lens.
The first results with this new 42.5 mm are quite good without being outstanding. The images are crisp and stitched in the center at full aperture of f / 1.2. This sensation of sharpness fades as one approaches the edges.
