I've had the same problem. My Amazon order is 2-5 weeks delayed and NO store ANYWHERE has it in stock. They've got the HD and DVD versions. My friend Gord at tvshowsondvd.com told me that even the review copies are late. *sigh* This isn't fair to make it unavailable to consumers and then complain about sales.
They have stated to remain on both throughout the holiday season but also have said they are talking to both parties....but that has nothing to do with smallville or the other warner releases this week being hard to find They just had a big update to their systems and are having issues with getting them cut and sent out...(I work at Best Buy). We were actually sent all the way up to the Sept 11 releases from warner back in the beginning of august...this would be the first week of shipments since the upgrade and they are experiencing problems....they tried to send them in advance to avoid these...guess they underestimated what would arise from upgrading
I belive the Blu Ray one comes out on the 18th of Dec. I bought Heros and Nip / Tuck season 4 and in one of the box sets has the release dates of DVD/HD movies and Smallville being one. I kinda want the Blu Ray one but the dvds are already in store and might just pick it up. I have all the other seasons on dvd anyways...maybe if they release a Smallville greatest hit or collection on Blu Ray Ill buy it.
