Damn, that's pretty surprising, maybe even shocking. Freak it, let Pj take the helm like he should have from the very beginning, this is his baby, at least the world that's created will be consistent, and he can have the same crew that has intimate knowledge of what was done with the Lotr trilogy.
I never understood the move to have someone else come in and direct these films, Del Toro was like an outsider in that world. He's a terrific director( and artist also) and i'm sure he would have done something special but this just may be a blessing in disguise for both parties.
This is Pj's baby, time for him to take over and totally focus and getting this thing done
