Every TV spot said the 13th is the release date for some reason. That must have been a big factor in the rather tepid OD and pretty much no drop on Thursday.
Except AUS and CHN, pretty much every market opened on wed or will open on thu. I base my conclusion on supposedly (i trust it the poster didn't just talk out of his ass) weaker than expected presales in UK and Germany and the fact that despite a decade of inflation and 3d it didn't top ROTK's OD in NZ.
