Like many people said. You can't have a SA with the KR client if you don't have a KR client.
The KR client is what now a year old or more?
You can easily tell whats happening to the game by the expansion releases. Early on you had a major expansion about every year. ML was released in august almost 3 years ago in 2005, and it actually was released early with SOOO many problems and bugs, many of which havent' even been fixed yet, or until recently (3 years to fix ML bugs.. how VERY sad).
So, suddenly after ML, expansions stopped. They started working on a new client because they wanted to update the game some. 2 years later they came out with the basic KR beta. 2 YEARS. And it was just a beta. A year later its now, and KR is still basically in beta. No work being done on it, still tons of bugs, problems, and graphics that aren't even in the game yet. It doesn't take 3 years to do a beta on a new client, but it DOES if you don't have anyone working on it.
So, after 3 years from the last expansion, we have.. zilch. A half buggy new client that most people don't want to use because its still in beta. Still in testing. Still being worked on... sometimes.
And then you have a new expansion based on that new beta client, which can't come out until the new client is ready, and after 3 years, its still not ready. We already have things you can "BUY" which were suppose to be in the new expansion SA, such as 7th character and expanded housing. THey had to release that because they knew SA would never get out anytime soon, so they wanted money. They want to charge you the price of an expansion for you to get a 7th character slot and storage. HOW FRIGGIN lame. 30 bucks should be the price for a totally new expansion, not some measly 2 basic bonus. But thats EA now.
So, SA won't come out period. First, they can't even fix the client its based on, so how can you release the expansion. If the last expansion was 3 years ago, this next expansion will be at least another year or 2 because thats how long it will take to finish up with the major part of KR.
