I think the public perception of Wonder Woman is strong enough that she really wouldnt need to be introduced in any large way. DC generally has the edge in their characters existing in the public mind far better than the Marvel ones.
I totally agree with the first sentence.
The second sentence once held true. I'd say that edge has either dulled totally the past 10 years or it's about even. With the variety of Marvel movies from various studios and the cartoons airing on Disney channel with a new Avengers 'toon coming Marvel is very firmly rooted in the general public's awareness.
