doubt this. Warner Brothers has in the past gone to ridiculus extremes to keep this stuff under wraps.
For B V S they released 3 pictures of Superman Batman and Wonder woman...and for a good solid year even i belive at last years marketing summit just used those pictures over and over. No reason they couldn't have done more, just you know we need a kind of grainy Batman.
I doubt they would do just the all logo poster. Maybe they could, but you know maybe not.
That said...its not a bad logo at all. Like the fact that it does seem to have three dimensions which looks cool with its kinda mechanical feel, and i could see this working well.
