Then (realizing YANAL) is there any risk in waiting until someone truly

I don't believe that waiting weakens our claim, so long as it's true in fact
that the name "Wikipedia" is associated with us and that we defend this.
I mean that we would have to prove these facts regardless of whether we wait.
One potential risk in waiting is that we could be denied registration
because somebody else had already registered the trademark themselves.
The US Patent & Trademark Office generally will only check that
there are no conflicting registered marks. They will not investigate to
make sure that nobody else is using the mark. Instead, they provide
"notice" to the public by publishing applications, and if someone
raises legitimate objections, then the mark is not registered.
