I am planning on watching it, but I don't expect a very high quality product. The problem is Simcha Jacobovici has a reputation for making sensational "discoveries." These usually involve looking at the evidence (you might call it twisting the evidence) in a very different way than what is accepted by scientists. He will leave out evidence that contradicts his "hypothesis" and build a very convincing story based on a part of the data. The atrocities are documented in this review of Exodus Decoded, which also includes a dialogue with Simcha Jacobovici, so read the whole thing. However I think this quote sums it up nicely.
By the end of the film I grew weary of the piling-on of amazing discoveries. Each one is historically dubious and requires a willing suspension of disbelief.
I expect this upcoming film will have many of the same problems.
Update: I forgot to mention one small detail. The tomb they claimed to have discovered wasn't empty. In the tomb there was a box labled "Jesus son of Joseph" and box labeled "Judah son of Jesus" along with a box attributed to Mary Magdalene.
