dunno what to believe, some of it certainly could look it is not other would be a yes or a no or whatever.
Some of the stuff could ha been clipped in from here and there from other games, and yet not it looks very close to the SWG interrior.
As for bespin posibly being a lag hell then well it could be the intro movie you see there everytime you enter just like at mustafar.
As for a zone with clouds it certainly can be done, I know from own experience in how to add poor quality stuff far away that will look good at great distance and then adding a cubic room inside a more huge cube that would make it look alot like horizont etc.
But I got my doubts alot on if it is right or not, it would be kinda very beta if it is true though, and would love to have a chiss alt and all but whatever, whenever it comes to it, then it is not important.
I have to mention though that there has been done quite alot of server maintaince and posible upgrades, so it could be that the server would be geared for all this through the next 5-6 months, they are about to shut down alot of the low pop servers as it is now, mainly because people stick to the good servers, eg Starsider varies from medium to heavy populated in the right hours and most of the time around medium when people gets on, so there has to be an increase to people who play the game as it is and that stuff like this could be quite a posibility since now they have found out what would make people actually play the game.
All crafting needs is getting back up at a much more increased rate than before, it is not NGE anymore for an instance, it is what it was supposed to be whenever they launched it all, those who made it run again really has done an effort, but it would had been better if they had released it all today rather than developing it over years.
