The PS3 version has not long been out, but the X360 version has been out since late last year. No word yet as to what extras will be included in this edition, but it is due out in just 7 days time (19th August 2011) and priced at £29.99, despite the fact that the standard X360 version can already be bought brand new from most retailers for half that price
EDIT: The X360 version has since been reduced to £19.99, although the newer PS3 version remains £29.99
