NAB 2016 has turned out to be subdued in product announcements when it comes to cameras. Sure there are a few of not but nothing earth shattering for price conscious video enthusiasts. The Sony FS5 is still a great camera and the new firmware to be released in May-June 2016 will give it more features and power.
The New firmware update v2.0 will be free but if you want the high frame rate capabilities you will need an external recorder and $600 USD or $500 Euros. Also you will need an external recorder to handle the RAW output.
