Preview of Fast and Furious leaked?

Although the release of the next Fast and Furious film will be delayed due to the tragic death of Paul Walker, the final version is said to be finished by April 2015. Here’s a scene from the upcoming movie:

Everybody calm down, this is not a leaked illegal trailer as many have thought, it is an official preview included in the F&F 6 Blue Ray version. It's just someone (probably from Poland?) thought that such a prank would be funny. Anyway, it is strange to see this preview.

Quite morbidly, the scene is set in a cemetery and Paul Walker, or more precisely his character Brian O’Connor, can be seen in a group of mourners. The illegal race drivers gather to say farewell to a supporting character, Han Iue, who died in F&F 6. What everybody wants to know is how the makers manage to turn the unfinished film into a complete story. We can only guess. Some are sure O’Connor will die, too, others believe he will retire from racing. It certainly isn’t easy to make the story evolve without Walker, as he was the steadiest character of the series.

The film was originally scheduled for release in the summer of 2014 as you can see at the end of the clip, but it obviously won’t be finished this year. It will be a wonder if it makes it in 2015.
