"X-Men: First Class" Teaser In "The Green Hornet"?

Above is another logo for the upcoming "X-Men: First Class". So supposedly a teaser trailer for Matthew Vaughns "X-Men: First Class" film will be shown before "The Green Hornet" plays in cinemas. It's attached to it. How awesome is that? Fox havent made an official announcement yet to say that it is true or not.

UPDATE: Fox have confimed that this is not happening. We still have to wait 4-6 weeks.
