Here in the Netherlands I noticed fast PS3 sales but also fast restocks, slow 360 sales and interested customers being told to buy Wii's as fast as possible because they 'sell out quickly', some shops carry signs 'sold out, pre-order now' (but also some online stores like otto.nl have them in stock, 24 hour delivery at time of writing).
Ratchet & Clank moved back up to spot 3 on the PS3 charts probably indicating the new Uncharted / R&C bundles are selling well.
