The cinema version of Die Hard 4.0 was still a 15 actually (although the same version was a PG-13 in the US). The BBFC didn't like the kung-fu violence used by Maggie Q's character, and the "Yippee-ki-yay motherf*cker" line pushed it beyond the limit for 12A (even though it's only just audible).
Even though it was still a pussified version of Die Hard i'm glad that it was a 15, at least there were no kiRAB in the theatre!
The 'Ultimate Action' DVD version definitely ups the language and violence though. But i think you'll find that the film was shot with PG-13 in mind, it was NOT cut for the theatre version, they merely filmed a bunch of alternate takes complete with swearing/violence with the intention of releasing it on DVD.
