firstly - sorry if this has already been discussed, but, will there be any difference between the R1 and R2 versions of the collectors edition (with the Argonath bookends). i have pre-ordered the R2 version from play at £32.99. their website states that all extras are subject to confirmation. the R1 version also states that all extras are subject to confirmation, but the set is listed at £46.99, which makes me think that there is a significant difference in content. DVDsoon lists the R1 version as having the national geographic disc included, but i cant seem to find anywhere that lists finalised R2 content. i emailed play, but they said "we cant comment" !!!! does ayone have any ideas ????
