Hope all you would-be PSP buyers out there are into that PSP-3000 Ratchet & Clank Entertainment Pack that just went on sale a couple weeks ago, because it's going to be the only bundle available from here on out. That's the word straight from Sony, which says that "ongoing discussions" with retailers have led it to kill the previously-announced $169 4GB Memory PSP-3000 bundle in favor of offering a single SKU -- although the company helpfully points out that you can still score a 4GB PSP Memory Stick PRO Duo for an additional $45. Yeah, thanks for the tip, guys. The current Mystic Silver bundle will be joined by a Piano Black version sometime in December, so you're not totally limited option-wise, but we're not exactly pumped about throwing extra money at a game we don't necessarily want -- we'd happily drop the extra cash on a non-interlaced screen, however.
