Just US packs really mate, mostly from sony.
Really not worth the specific investment tbh and i see them becoming even less common going forward. Sony cancelled the last 2 they planned to release, underworld blood wars and res evil final chapter. Sony does seem to be backing out of 4k entirely through mind you.
Ghostbusters 2016
Angry birds
passengers
Kong - best buy exclusive
Billy lynn
Star trek beyond - amazon US exclusive
Dredd
And the only reason it was included with dredd was afasik there was only a single 2d/3d blu issue of it in the US, which was included here as part of the standard 4k blu combo pack. I imagine it'll be region locked being lionsgate though.
