John Koller, hardware director of Sony Computer Entertainment America has said that due to significant interest in the PSP 3000 Ratchet & Clank Size Matters pack, they will be continuing to sell the Mystic Silver pack in North America, with Piano Black becoming available in December.

Because of the significant interest, the PSP 3000 4GB pack has been cancelled. Many retailers cancelled pre-orders for the pack over the weekend. Those interested in a bigger memory stick can purchase a 4GB Sony memory stick from fall for $44.99.

Other retailers such as Amazon are already offering the 4GB Sony memory stick for a lower price and have done for a while.
