   Not if new elements are based on significant use cases. Considering
the popularity of YouTube and other video sites, I'd say that a use case
for <video> is a safe bet.

   Also keep in mind that, using your logic, we should eliminate <img>
because you can use <object> instead. (In fact, that makes more sense
because <object> has better fallback than <img>, whereas <video> has
equivalent fallback.)

   I would not consider pages with both SVG and Flash all that common.
It's far more likely that you'd see video and Flash. In fact, they may
be using Flash to play videos, so because there isn't a <video> element
to allow native, integrated video support, there may be no means of
determining of something is even a video without analyzing the Flash
data itself.

   Another issue is that while Flash may eventually disappear from the
'Net, video isn't going anywhere.
