The orignal story came from there so you should take the news with a grain of salt. There is also some people at the Gaming-age forums discussing (crying) about it...
In response to the original "news" report...
"Yes folks, it's true. If you haven't heard it already, Sega's latest Playstation 2 title, Rez, was officially discontinued a few days after its release, for reasons unknown.
We've received quite a few emails asking for a reliable source to be listed, so I thought I would elaborate on the situation. I also work at Electronics Boutique, and we received the game initially in a rather small supply (only a few copies). Whereas normally, we get quite a few copies of a brand new title. Strange, but whatever. We placed the game on the shelf, and it proceeded for a few days to not sell a single copy. Then, one day, I wanted to see if we had sold any copies while I had been off, so I looked it up in the computer. That's when I saw it. A "D" listed next to the game's name. D stands for Discontinued for those of you who didn't know. Well, this is a pretty strange occurance, to say the least. I thought perhaps it may be an error. So I, along with the store manager called around to a few other retail gaming outlets to verify this listing. Sure enough, they all were surprised to learn that their computers also said that this new game was already discontinued. Well, that lit the fires. I waited more than a week to see if the status of the game would change, but to no avail. That's when I realized that Rez, a fairly cool game in its own right, had gone the way of tons of other neglected titles that had their productions ceased with no notice or fanfare. Unfortunate, but fact.
By not officially releasing a press statement detailing the reasons behind the move, Sega of America seems trying to cover up the fact that their latest high-profile PS2 title didn't last more than a single week in distribution. Obviously, this information doesn't bode well for Sega's "biggest 3rd party" mantra that's been tossed around lately, which could reasonably explain the thinking behind Sega's decision to keep the move quiet. Whatever the case, there are still copies of the game's initial shipments to be found in retail stores across North America, and you may want to run out and grab one, seeing how as you won't be seeing a second shipment any time soon.
Can we say... Instant Collector's Item? "
I post this so that JUST IN CASE someone out there is looking for a PS2 version and are sitting on their hands, to go get it. If this story turns out to be true, you'll thank me later.
