Not sure if this was posted, but it comes from PC Gamer's website on how the release date is tied to the beta testing...
EAs Frank Gibeau has recently told CVG that fan reaction to the beta will determine when the The Old Republic will be released. Gibeau said EA wanted a smooth, problem free launch for the MMO, echoing the sentiment displayed when we discussed Star Wars: The Old Republic pre-orders with Biowares Dr Greg Zeschuck at Gamescom.
[The release date] is definitely tied to the beta test feedback thats ongoing and so far, so good. said Gibeau. We feel good about the date that were heading towards but
you could have a Crazy Ivan show up in the September/October beta test and be like, wow, Ive got to fix that.
EA and Bioware are determined to try and avoid the launch issues that have plagued other MMOs. Gibeau told the website: We dont want to happen to us what happened to WoW and a couple of other services where in the first week there were queues trying to get on to the servers, the entire service crashed we dont want that to happen. So we need to nail and make sure that its up 24/7 and its high quality.
Pre-orders for the game are limited. An EA representative told Gamasutra they are limiting launch quantities of Star Wars: The Old Republic to ensure players have a smooth and high quality game experience and service at launch.
We spoken to Bioware creative officer Dr. Greg Zeschuk about Star Wars: The Old Republic pre-orders. He admitted that their servers could be jam-packed come release, saying, If you dont pre-order a copy you may not even get in in the first month just because theres so many people on.
Zeschuk also mentioned that Bioware were doing their best to ensure that The Old Republic avoided the problematic launches of other MMOs but admitted they couldnt rule them out completely: Were trying to make sure we dont have huge queues, I mean thats something that WoW and other games had, its part of life, theres only so many people get on. I mean if you happen to log on at precisely the wrong time there might be a small queue but it wont be huge. Were still optimising the size and the servers to make sure thats not big experience problem. We dont want to be plugged in waiting for ten minutes or whatever to play games on time.
