Unfortunately the PSVita/PS4 patch will not be released before the Christmas target.
Last minute issues with PSN sign in procedures that had not been apparent previously have meant that, although resolved, the deadline for submission to make a pre-Christmas release has now been missed.
Dino and the team offer their apologies to everyone that has been waiting and thank you all for your patience and support.
The new targeted release is in the first week or two of January when Sony re-open.
