The next major version of BPBible is intended to use XULRunner with
wxWebConnect.

In actual practice, I think SVG support and HTML 5 support have a lot in
common, since most browsers will support a subset of both rather than the
full thing (many elements of HTML 5 have been around for a long time as
well).  I don't have a clear idea of which subsets are supported by which
browsers (I would assume the useful parts - but that will probably apply to
HTML 5 as well).  Static images are probably a better chance than dynamic
images.  As an example, the Mozilla page is at
http://www.mozilla.org/projects/svg/status.html.
