In September 2012, Sony acquired WDR specialist Pixim.
Though Pixim 'powered' cameras are still being sold, there's hardly any marketing / promotion from Pixim or Sony about Pixim.
We asked Sony and Pixim's partners for a status report.
Sony responded by saying, "There is no news yet available on new Sony image sensors using Pixim technology."
Sony / Pixim partners confirmed that Sony is still actively selling existing Pixim chips (like Seawolf and Orca) but that development of new products (e.g., HD Pixim WDR cameras) is either halted or stopped.
It appears that the era of Pixim pixel based WDR is ending, having been supplanted by numerous multi-exposure HD WDR offerings.
Ironically, and maybe understandably, WDR in video surveillance cameras have never been stronger than they are today, with most manufacturers offering credible HD WDR cameras (e.g., see WDR Shootout 2013).
