Happy New Year to all of you! For what it's worth, I've just filed https://bugzil.la/1328534 to keep track of the SVG 2 implementation in Gecko. It's probably still missing a lot of features and changes, so if you see or file a SVG 2 related bug, please make it a blocker of that bug! I am really wondering who were the people at Google, Microsoft and Mozilla (and Apple?) providing the feedback and would like to know about their opinion regarding their implementation interest and the future of SVG in general.
