Well the original conversation did include keeping all future updates open provided the ports were up to the standards of the original. ;P However there's no current news on my hint. 
It was not merely a conversation, but a public commitment to donors. Here is the full quote:
"If this project is successfully funded, and as long as the resulting ports stay true to the original version of the Odyssey Web Browser in terms of user experience and feature sets,
Fabien Coeurjoly plans to share all source code
that he will develop himself for future versions of Odyssey Web Browser for free."
