| Dianko said: Well, gaf is extrapolating based on old charttrack numbers saying Halo Wars sold about 80k, and that Killzone 2 is somewhere between that and 108k (GT5P week 1) for UK. |
Chart-Track have since given Halo 3 first week at 411k (extrapolated). They're basing it off of the "sold to a third of X360's 1.4m installed base" given in Chart-Track's blurb during Halo 3 release week which was rounded up by quite a bit.
108k was non-extrapolated first week number for GT5:P, it's 120k extrapolated (Chart-Track cover 90% of UK retail).
