As far as I'm aware, the Journey Collector's Edition won't be coming out in Europe, making an import your only option. However, 365 seems to have dealt with the importing bit themselves, offering an attractive £23.99 price including delivery. This NTSC (region free) collection contains Journey, Flower, flOw, three extra games and some bonus content, making it a bit of a bargain for thatgamecompany fans.
CAVEAT: the bundled free month of PlayStation Plus and exclusive avatars can only be downloaded if you have an NTSC account, being as download codes are region specific. Even though games aren't. Haven't quite puzzled that one out yet, to be honest.
